When a user tries to rename a branch that has a "bad name" (e.g.,
starts with a '-') then we warn them that the misnamed branch has
been renamed "away". A similar message is shown when trying to create
a copy of a misnamed branch even though it doesn't remove the misnamed
branch. This is not correct and may confuse the user.
So, update the warning message shown to be more precise that only a copy
of the misnamed branch has been created. It's better to show the warning
message than not showing it at all as it makes the user aware of the
presence of a misnamed branch.

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.
Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.
By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree. Prior to
557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.
Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.
Fix this by explicitly reading the index during the setup of diff-tree.

Introduce fetch-object, providing the ability to fetch one object from a
promisor remote.
This uses fetch-pack. To do this, the transport mechanism has been
updated with 2 flags, "from-promisor" to indicate that the resulting
pack comes from a promisor remote (and thus should be annotated as such
by index-pack), and "no-dependents" to indicate that only the objects
themselves need to be fetched (but fetching additional objects is
nevertheless safe).
Whenever "no-dependents" is used, fetch-pack will refrain from using any
object flags, because it is most likely invoked as part of a dynamic
object fetch by another Git command (which may itself use object flags).
An alternative to this is to leave fetch-pack alone, and instead update
the allocation of flags so that fetch-pack's flags never overlap with
any others, but this will end up shrinking the number of flags available
to nearly every other Git command (that is, every Git command that
accesses objects), so the approach in this commit was used instead.
This will be tested in a subsequent commit.

Currently, Git does not support repos with very large numbers of objects
or repos that wish to minimize manipulation of certain blobs (for
example, because they are very large) very well, even if the user
operates mostly on part of the repo, because Git is designed on the
assumption that every referenced object is available somewhere in the
repo storage. In such an arrangement, the full set of objects is usually
available in remote storage, ready to be lazily downloaded.

Commit 74ed43711f (grep: enable recurse-submodules to work on <tree>
objects, 2016-12-16) taught 'tree_entry_interesting()' to be able to
match across submodule boundaries in the presence of wildcards. This is
done by performing literal matching up to the first wildcard and then
punting to the submodule itself to perform more accurate pattern
matching. Instead of introducing a new flag to request this behavior,
commit 74ed43711f overloaded the already existing 'recursive' flag in
'struct pathspec' to request this behavior.
This leads to a bug where whenever any other caller has the 'recursive'
flag set as well as a pathspec with wildcards that all submodules will
be indicated as matches. One simple example of this is:
git init repo
cd repo
git init submodule
git -C submodule commit -m initial --allow-empty
touch "[bracket]"
git add "[bracket]"
git commit -m bracket
git add submodule
git commit -m submodule
git rev-list HEAD -- "[bracket]"
Fix this by introducing the new flag 'recurse_submodules' in 'struct
pathspec' and using this flag to determine if matches should be allowed
to cross submodule boundaries.

Move print_commit_summary() from builtin/commit.c to sequencer.c so it
can be shared with other commands. The function is modified by
changing the last argument to a flag so callers can specify whether
they want to show the author date in addition to specifying if this is
an initial commit.
If the sequencer dies in print_commit_summary() (which can only happen
when cherry-picking or reverting) then neither the todo list nor the
abort safety file are updated to reflect the commit that was just
made. print_commit_summary() can die if:
- The commit that was just created cannot be found or parsed.
- HEAD cannot be resolved either because some other process is
updating it (which is bad news in the middle of a cherry-pick) or
because it is corrupt.
- log_tree_commit() cannot read some objects.
In all those cases dying will leave the sequencer in a sane state for
aborting; 'git cherry-pick --abort' will rewind HEAD to the last
successful commit before there was a problem with HEAD or the object
database. If the user somehow fixes the problem and runs 'git
cherry-pick --continue' then the sequencer will try and pick the same
commit again which may or may not be what the user wants depending on
what caused print_commit_summary() to die. If print_commit_summary()
returned an error instead then update_abort_safety_file() would try to
resolve HEAD which may or may not be successful. If it is successful
then running 'git rebase --abort' would not rewind HEAD to the last
successful commit which is not what we want.

When `log --decorate` is used, git will decorate commits with all
available refs. While in most cases this may give the desired effect,
under some conditions it can lead to excessively verbose output.
Introduce two command line options, `--decorate-refs=<pattern>` and
`--decorate-refs-exclude=<pattern>` to allow the user to select which
refs are used in decoration.
When "--decorate-refs=<pattern>" is given, only the refs that match the
pattern are used in decoration. The refs that match the pattern when
"--decorate-refs-exclude=<pattern>" is given, are never used in
decoration.
These options follow the same convention for mixing negative and
positive patterns across the system, assuming that the inclusive default
is to match all refs available.
(1) if there is no positive pattern given, pretend as if an
inclusive default positive pattern was given;
(2) for each candidate, reject it if it matches no positive
pattern, or if it matches any one of the negative patterns.
The rules for what is considered a match are slightly different from the
rules used elsewhere.
Commands like `log --glob` assume a trailing '/*' when glob chars are
not present in the pattern. This makes it difficult to specify a single
ref. On the other hand, commands like `describe --match --all` allow
specifying exact refs, but do not have the convenience of allowing
"shorthand refs" like 'refs/heads' or 'heads' to refer to
'refs/heads/*'.
The commands introduced in this patch consider a match if:
(a) the pattern contains globs chars,
and regular pattern matching returns a match.
(b) the pattern does not contain glob chars,
and ref '<pattern>' exists, or if ref exists under '<pattern>/'
This allows both behaviours (allowing single refs and shorthand refs)
yet remaining compatible with existent commands.
