git rev-parse has several options which print various paths. Some of
these paths are printed relative to the current working directory, and
some are absolute.
Normally, this is not a problem, but there are times when one wants
paths entirely in one format or another. This can be done trivially if
the paths are canonical, but canonicalizing paths is not possible on
some shell scripting environments which lack realpath(1) and also in Go,
which lacks functions that properly canonicalize paths on Windows.
To help out the scripter, let's provide an option which turns most of
the paths printed by git rev-parse to be either relative to the current
working directory or absolute and canonical. Document which options are
affected and which are not so that users are not confused.
This approach is cleaner and tidier than providing duplicates of
existing options which are either relative or absolute.
Note that if the user needs both forms, it is possible to pass an
additional option in the middle of the command line which changes the
behavior of subsequent operations.

Change the documentation for the various %(trailers) options so it
isn't repeating part of the documentation for "only" about how boolean
values are handled. Instead, let's split the description of that into
general documentation at the top.
It then suffices to refer to it by listing the options as
"opt[=<BOOL>]". I'm also changing it to upper-case "[=<BOOL>]" from
"[=val]" for consistency with "<SEP>"
It took me a couple of readings to realize that these options were
referring back to the "only" option's treatment of boolean
values.

Add a "key_value_separator" option to the "%(trailers)" pretty format,
to go along with the existing "separator" argument. In combination
these two options make it trivial to produce machine-readable (e.g. \0
and \0\0-delimited) format output.
As elaborated on in a previous commit which added "keyonly" it was
needlessly tedious to extract structured data from "%(trailers)"
before the addition of this "key_value_separator" option. As seen by
the test being added here extracting this data now becomes trivial.

Add support for a "keyonly". This allows for easier parsing out of the
key and value. Before if you didn't want to make assumptions about how
the key was formatted. You'd need to parse it out as e.g.:
--pretty=format:'%H%x00%(trailers:separator=%x00%x00)' \
'%x00%(trailers:separator=%x00%x00,valueonly)'
And then proceed to deduce keys by looking at those two and
subtracting the value plus the hardcoded ": " separator from the
non-valueonly %(trailers) line. Now it's possible to simply do:
--pretty=format:'%H%x00%(trailers:separator=%x00%x00,keyonly)' \
'%x00%(trailers:separator=%x00%x00,valueonly)'
Which at least reduces it to a state machine where you get N keys and
correlate them with N values. Even better would be to have a way to
change the ": " delimiter to something easily machine-readable (a key
might contain ": " too). A follow-up change will add support for that.
I don't really have a use-case for just "keyonly" myself. I suppose it
would be useful in some cases as "key=*" matches case-insensitively,
so a plain "keyonly" will give you the variants of the keys you
matched. I'm mainly adding it to fix the inconsistency with
"valueonly".

The 'clean' target is still noticeably slow on cygwin, despite the

second invocation of 'make clean' below:
$ make clean >/dev/null 2>&1
$ make clean
...
make[1]: Entering directory '/home/ramsay/git/Documentation'
make[2]: Entering directory '/home/ramsay/git'
make[2]: 'GIT-VERSION-FILE' is up to date.

...
$
has been timed at 12.364s on my laptop (an old core i5-4200M @ 2.50GHz,
8GB RAM, 1TB HDD).
Notice that the 'clean' target is making a nested call to the parent
Makefile to ensure that the GIT-VERSION-FILE is up-to-date (prior to
the previous patch, there would have been _two_ such invocations).
This is to ensure that the $(GIT_VERSION) make variable is set, once
that file had been included. However, the 'clean' target does not use
the $(GIT_VERSION) variable, directly or indirectly, so it does not
have any affect on what the target removes. Therefore, the time spent
on ensuring an up to date GIT-VERSION-FILE is wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include ../GIT-VERSION-FILE' when the
target is not 'clean'. (This drops the time down to 10.361s, on my laptop,
giving an improvement of 16.20%).

Notice that, since the 'doc.dep' file does not exist, make takes the
time (about 8s) to generate several files in order to create the doc.dep
include file. (If an 'include' file is missing, but a target for the
said file is present in the Makefile, make will execute that target
and, if that file now exists, throw away all its internal data and
re-read and re-parse the Makefile). Having spent the time to include
the 'doc.dep' file, the 'clean' target immediately deletes those files.
The document dependencies specified in the 'doc.dep' include file,
expressed as make targets and prerequisites, do not affect what the
'clean' target removes. Therefore, the time spent in generating the
dependencies is completely wasted effort.
In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include doc.dep' when the target is

The introductory part of the "git config --help" mentions the
optional value-pattern argument, but give no hint that it can be
something other than a regular expression (worse, it just says
"POSIX regexp", which usually means BRE but the regexp the command
takes is ERE). Also, it needs to be documented that the '!' prefix
to negate the match, which is only mentioned in this part of the
document, works only with regexp and not with the --fixed-value.

The 'git config' builtin takes a 'value-pattern' parameter for several
actions. This can cause confusion when expecting exact value matches
instead of regex matches, especially when the input string contains
metacharacters. While callers can escape the patterns themselves, it
would be more friendly to allow an argument to disable the pattern
matching in favor of an exact string match.
Add a new '--fixed-value' option that does not currently change the
behavior. The implementation will be filled in by later changes for
each appropriate action. For now, check and test that --fixed-value
will abort the command when included with an incompatible action or
without a 'value-pattern' argument.
The name '--fixed-value' was chosen over something simpler like
'--fixed' because some commands allow regular expressions on the
key in addition to the value.

The 'value_regex' argument in the 'git config' builtin is poorly named,
especially related to an upcoming change that allows exact string
matches instead of ERE pattern matches.
Perform a mostly mechanical change of every instance of 'value_regex' to
'value_pattern' in the codebase. This is only critical for documentation
and error messages, but it is best to be consistent inside the codebase,
too.
For documentation, use 'value-pattern' which is better punctuation. This
affects Documentation/git-config.txt and the usage in builtin/config.c,
which was already mixed between 'value_regex' and 'value-regex'.
I gave some thought to leaving the value_regex variables inside config.c
that are regex_t pointers. However, it is probably best to keep the name
consistent with the rest of the variables.
This does not update the translations inside the po/ directory, as that
creates conflicts with ongoing work. The input strings should
automatically update through automation, and a few of the output strings
currently use "[value_regex]" directly.

Emit a trace2 error event whenever warning() is called, just like when
die(), error(), or usage() is called.
This helps debugging issues that would trigger warnings but not errors.
In particular, this might have helped debugging an issue I encountered
with commit graphs at $DAYJOB [1].
There is a tradeoff between including potentially relevant messages and
cluttering up the trace output produced. I think that warning() messages
should be included in traces, because by its nature, Git is used over
multiple invocations of the Git tool, and a failure (currently traced)
in a Git invocation might be caused by an unexpected interaction in a
previous Git invocation that only has a warning (currently untraced) as
a symptom - as is the case in [1].

A review exchange may begin with a reviewer asking "what did you
mean by this phrase in your log message (or here in the doc)?", the
author answering what was meant, and then the reviewer saying "ah,
that is what you meant---then the flow of the logic makes sense".
But that is not the happy end of the story. New contributors often
forget that the material that has been reviewed in the above exchange
is still unclear in the same way to the next person who reads it,
until it gets updated.
While we are in the vicinity, rephrase the verb "request" used to
refer to comments by reviewers to "suggest"---this matches the
contrast between "original" and "suggested" that appears later in
the same paragraph, and more importantly makes it clearer that it is
not like authors are to please reviewers' wishes but rather
reviewers are merely helping authors to polish their commits.

`init_grep_defaults()` fills a `static struct grep_opt grep_defaults`.
This struct is then used by `grep_init()` as a blueprint for other such
structs. Notably, `grep_init()` takes a `struct repo *` and assigns it
into the target struct.
As a result, it is unnecessary for us to take a `struct repo *` in
`init_grep_defaults()` as well. We assign it into the default struct and
never look at it again. And in light of how we return early if we have
already set up the default struct, it's not just unnecessary, but is
also a bit confusing: If we are called twice and with different repos,
is it a bug or a feature that we ignore the second repo?
