When shortlog processes a commit using its internal traversal, it may
pretty-print the subject line for the summary view. When we do so, we
set the "print_email_subject" flag in the pretty-print context. But this
flag does nothing! Since we are using CMIT_FMT_USERFORMAT, we skip most
of the usual formatting code entirely.
This flag is there due to commit 6d167fd7cc (pretty: use
fmt_output_email_subject(), 2017-03-01). But that just switched us away
from setting an empty "subject" header field, which was similarly
useless. That was added by dd2e794a21 (Refactor pretty_print_commit
arguments into a struct, 2009-10-19). Before using the struct, we had to
pass _something_ as the argument, so we passed the empty string (a NULL
would have worked equally well).
So this setting has never done anything, and we can drop the line. That
shortens the code, but more importantly, makes it easier to reason about
and refactor the other users of this flag.

Code simplification by getting rid of code that sets an environment
variable that is no longer used.
* pw/rebase-i-ignore-cherry-pick-help-environment:
rebase -i: stop setting GIT_CHERRY_PICK_HELP
When 'git am' or 'git rebase --apply' encounter a conflict, they show a
message instructing the user how to continue the operation. This message
can't be disabled.
Use ADVICE_MERGE_CONFLICT introduced in the previous commit to allow
disabling it. Update the tests accordingly, as the advice output is now
on stderr instead of stdout. In t4150, redirect stdout to 'out' and
stderr to 'err', since this is less confusing. In t4254, as we are
testing a specific failure mode of 'git am', simply disable the advice.
Note that we are not testing that this advice is shown in 'git rebase'
for the apply backend since 2ac0d6273f (rebase: change the default
backend from "am" to "merge", 2020-02-15).

Extending the previous step, this allows the whitespace placed after
the value before the "# comment message" to be tweaked by tweaking
the preprocessing rule to:
* If the given comment string begins with one or more whitespace
characters followed by '#', it is passed intact.
* If the given comment string begins with '#', a Space is
prepended.
* Otherwise, " # " (Space, '#', Space) is prefixed.
* A string with LF in it cannot be used as a comment string.
Unlike the previous step, which unconditionally added a space after
the value before writing the "# comment string", because the above
preprocessing already gives a whitespace before the '#', the
resulting string is written immediately after copying the value.
And the sanity checking rule becomes
* comment string after the above massaging that comes into
git_config_set_multivar_in_file_gently() must
- begin with zero or more whitespace characters followed by '#'.
- not have a LF in it.
I personally think this is over-engineered, but since I thought
things through anyway, here it is in the patch form. The logic to
tweak end-user supplied comment string is encapsulated in a new
helper function, git_config_prepare_comment_string(), so if new
front-end callers would want to use the same massaging rules, it is
easily reused.
Unfortunately I do not think of a way to tweak the preprocessing
rules further to optionally allow having no blank after the value,
i.e. to produce
[section]
variable = value#comment
(which is a valid way to say section.variable=value, by the way)
without sacrificing the ergonomics for the more usual case, so this
time I really stop here.

When git adds comments itself (like "rebase -i" todo list and
"commit -e" log message editor), it always gives a comment
introducer "#" followed by a Space before the message, except for
the recently introduced "git config --comment", where the users are
forced to say " this is my comment" if they want to add their
comment in this usual format; otherwise their comment string will
end up without a space after the "#".
Make it more ergonomic, while keeping it possible to also use this
unusual style, by massaging the comment string at the UI layer with
a set of simple rules:
* If the given comment string begins with '#', it is passed intact.
* Otherwise, "# " is prefixed.
* A string with LF in it cannot be used as a comment string.
Right now there is only one "front-end" that accepts end-user
comment string and calls the underlying machinery to add or modify
configuration file with comments, but to make sure that the future
callers perform similar massaging as they see fit, add a sanity
check logic in git_config_set_multivar_in_file_gently(), which is
the single choke point in the codepaths that consumes the comment
string.

Introduce the ability to append comments to modifications
made using git-config. Example usage:
git config --comment "changed via script" \
--add safe.directory /home/alice/repo.git
based on the proposed patch, the output produced is:
[safe]
directory = /home/alice/repo.git #changed via script
Users need to be able to distinguish between config entries made
using automation and entries made by a human. Automation can add
comments containing a URL pointing to explanations for the change
made, avoiding questions from users as to why their config file
was changed by a third party.
The implementation ensures that a # character is unconditionally
prepended to the provided comment string, and that the comment
text is appended as a suffix to the changed key-value-pair in the
same line of text. Multi-line comments (i.e. comments containing
linefeed) are rejected as errors, causing Git to exit without
making changes.
Comments are aimed at humans who inspect or change their Git
config using a pager or editor. Comments are not meant to be
read or displayed by git-config at a later time.

In git-restore we need to free the pathspec and pathspec_from_file

A simple fix could be to free them in cmd_restore, after the call to
checkout_main returns, like we are doing [1][2] in the sibling function
cmd_checkout.
However, we can do even better.
We have git-switch and git-restore, both of them spin-offs[3][4] of
git-checkout. All three are implemented as thin wrappers around
checkout_main. Considering this, it makes a lot of sense to do the
cleanup closer to checkout_main.
Move the cleanups, including the new_branch_info variable, to
checkout_main.

When using "git checkout" to recreate merge conflicts or merge
uncommitted changes when switching branch "--conflict" sensibly implies
"--merge". Unfortunately the way this is implemented means that "git
checkout --conflict=diff3 --no-merge" implies "--merge" violating the
usual last-one-wins rule. Fix this by only overriding the value of
opts->merge if "--conflicts" comes after "--no-merge" or "-[-no]-merge"
is not given on the command line.
The behavior of "git checkout --merge --no-conflict" is unchanged and
will still merge on the basis that the "-[-no]-conflict" options are
primarily intended to affect the conflict style and so "--no-conflict"
should cancel a previous "--conflict" but not override "--merge".

Passing an invalid conflict style name such as "--conflict=bad" gives
the error message
error: unknown style 'bad' given for 'merge.conflictstyle'
which is unfortunate as it talks about a config setting rather than
the option given on the command line. This happens because the
implementation calls git_xmerge_config() to set the conflict style
using the value given on the command line. Use the newly added
parse_conflict_style_name() instead and pass the value down the call
chain to override the config setting. This also means we can avoid
setting up a struct config_context required for calling
git_xmerge_config().
The option is now parsed in a callback to avoid having to store the
option name. This is a change in behavior as now
git checkout --conflict=bad --conflict=diff3
will error out when parsing "--conflict=bad" whereas before this change
it would succeed because it would only try to parse the value of the
last "--conflict" option given on the command line.

We'd like to eventually support multi-byte comment prefixes, but the
comment_line_char variable is referenced in many spots, making the
transition difficult.
Let's start by storing the character in a NUL-terminated string. That
will let us switch code over incrementally to the string format, and we
can easily support the existing code with a macro wrapper (since we'll
continue to allow only a single-byte prefix, this will behave
identically).
Once all references to the "char" variable have been converted, we can
drop it and enable longer strings.
We'll still have to touch all of the spots that create or set the
variable in this patch, but there are only a few (reading the config,
and the "auto" character selector).

When core.commentChar is set to "auto", we check a set of candidate
characters against the proposed buffer to see which if any can be used
without ambiguity. But before we do that, we optimize for the common
case that the default "#" is fine by just seeing if it is present in the
buffer at all.
The way we do this is a bit subtle, though: we assign the candidate
character to comment_line_char preemptively, then check if it works, and
return if it does. The subtle part is that sometimes setting
comment_line_char is important (after we return, the important outcome
is the fact that we have set the variable) and sometimes it is useless
(if our optimization fails, we go on to do the more careful checks and
eventually assign something else instead).
To make it more clear what is happening (and to make further refactoring
of comment_line_char easier), let's check our candidate character
directly, and then assign as part of returning if it worked out.

We clarified how "clean.requireForce" interacts with the "--dry-run"
option in the previous commit, both in the implementation and in the
documentation. Even when "git clean" (without other options) is
required to be used with "--force" (i.e. either clean.requireForce
is unset, or explicitly set to true) to protect end-users from
casual invocation of the command by mistake, "--dry-run" does not
require "--force" to be used, because it is already its own
protection mechanism by being a no-op to the working tree files.
The previous commit, however, missed another clean-up opportunity
around the same area. Just like in the "--dry-run" mode, the
command in the "--interactive" mode does not require "--force",
either. This is because by going interactive and giving the end
user one more chance to confirm, the mode itself is serving as its
own protection mechanism.
Let's take things one step further, and unify the code that defines
interaction between "--force" and these two other options. Just
like we added explanation for the reason why "--dry-run" does not
honor "clean.requireForce", give an explanation for the reason why
"--interactive" makes "clean.requireForce" to be ignored.
Finally, add some tests to show the interaction between "--force"
and "--interactive". We already have tests that show interaction
between "--force" and "--dry-run", but didn't test "--interactive".

What -n actually does in addition to its documented behavior is

to make this more explicit in the code.
Improved implementation also stops to share single internal variable
'force' between command-line -f option and configuration variable
clean.requireForce, resulting in more clear logic.
Two error messages with slightly different text depending on if
clean.requireForce was explicitly set or not, are merged into a single
