Using format-patch with --commit-list-format different than shortlog,
causes the commit entry lines to wrap if they get longer than
MAIL_DEFAULT_WRAP (72 characters).
While this might be sensible for many when sending changes through
email, it forces this decision of wrapping on the user, reducing the
control granularity of --commit-list-format.
Teach generate_commit_list_cover() to respect commit entry line lengths
and place this wrapping rule on the "modern" preset format instead.

Before the recent changes to parse rev-list arguments inside of 'git
backfill', the builtin would take arbitrary arguments without complaint (and
ignore them). This was noticed and a patch was sent [1] which motivates
this change.

Note that the revision machinery can output an "ambiguous argument"
warning if a value not starting with '--' is found and doesn't make
sense as a reference or a pathspec. For unrecognized arguments starting
with '--' we need to add logic into builtin/backfill.c to catch leftover
arguments.

Previously, walk_objects_by_path() silently ignored pathspecs containing
wildcards or magic by clearing them. This caused all blobs to be
downloaded regardless of the given pathspec. Wildcard pathspecs like
"d/file.*.txt" are useful for narrowing which blobs to process (e.g.,
during 'git backfill').
Support wildcard pathspecs by making two changes:
1. Add an 'exact_pathspecs' flag to path_walk_context. When the
pathspec has no wildcards or magic, set this flag and use the
existing fast-path prefix matching in add_tree_entries(). When
wildcards are present, skip that block since prefix matching
cannot handle glob patterns.
2. Add a match_pathspec() check in walk_path() to filter out blobs
whose full path does not match the pathspec. This provides the
actual blob-level filtering for wildcard pathspecs.

The previous change allowed specifying revision arguments over the 'git
backfill' command-line. This created the opportunity for restricting the
initial commit set by filtering the revision walk through a pathspec. Other
than filtering the commit set (and thereby the root trees), this did not
restrict the path-walk implementation of 'git backfill' and did not restrict
the blobs that were downloaded to only those matching the pathspec.
Update the path-walk API to accept certain kinds of pathspecs and to
silently ignore anything too complex, for now. We will update this in the
next change to properly restrict to even complex pathspecs.
The current behavior focuses on pathspecs that match paths exactly. This
includes exact filenames, including directory names as prefixes. Pathspecs
containing wildcards or magic are cleared so the path walk downloads all
blobs, as before.
The reason for this restriction is to allow for a faster execution by
pruning the path walk to only trees that could contribute towards one of
those paths as a parent directory.
The test directory 'd/f/' (next to 'd/file*.txt') was prepared in a
previous commit to exercise the subtlety in prefix matching.

The existing implementation of 'git backfill' only includes downloading
missing blobs reachable from HEAD. Advanced uses may desire more general
commit limiting options, such as '--all' for all references, specifying a
commit range via negative references, or specifying a recency of use such as
with '--since=<date>'.
All of these options are available if we use setup_revisions() to parse the
unknown arguments with the revision machinery. This opens up a large number
of possibilities, only a small set of which are tested here.
For documentation, we avoid duplicating the option documentation and instead
link to the documentation of 'git rev-list'.
Note that these arguments currently allow specifying a pathspec, which
modifies the commit history checks but does not limit the paths used in the
backfill logic. This will be updated in a future change.

Prepare the test infrastructure for upcoming changes that teach 'git
backfill' to accept revision arguments and pathspecs.
Add test_tick before each commit in the setup loop so that commit dates
are deterministic. This enables reliable testing with '--since'.
Rename the 'd/e/' directory to 'd/f/' so that the prefix 'd/f' is
ambiguous with the files 'd/file.*.txt'. This exercises the subtlety
in prefix pathspec matching that will be added in a later commit.
Create a branched version of the test repository (src-revs) with:
- A 'side' branch merged into main, adding s/file.{1,2}.txt with
two versions (4 new blobs, 52 total from main HEAD).
- An unmerged 'other' branch adding o/file.{1,2}.txt (2 more blobs,
54 total reachable from --all).
This structure makes --all, --first-parent, and --since produce
meaningfully different results when used with 'git backfill'.

- builtin/fsck.c:cmd_fsck() which loops over all worktrees.
- builtin/receive-pack.c:update_worktree() which is called from
update() only when "worktree" is non-NULL.
- builtin/worktree.c:validate_no_submodules() which is called from
check_clean_worktree() and move_worktree(), both of which supply
a non-NULL worktree.
- reachable.c:add_rebase_files() which loops over all worktrees.

worktrees.

The function can_use_local_refs() prints a warning if there are no local
branches and HEAD is invalid or points to an unborn branch. As part of
the warning it prints the contents of ".git/HEAD". In a repository using
the reftable backend HEAD is not stored in the filesystem so reading
that file is pointless. In a repository using the files backend it is
unclear how useful printing it is - it would be better to diagnose the
problem for the user. For now, simplify the warning by not printing
the file contents and adjust the relevant test case accordingly. Also
fixup the test case to use test_grep so that anyone trying to debug a
test failure in the future is not met by a wall of silence.

The "is_current" member of struct worktree was added in 750e8a60d6
(worktree.c: mark current worktree, 2016-04-22) and was used in
8d9fdd7087 (worktree.c: check whether branch is rebased in another
worktree, 2016-04-22) to optionally skip the current worktree when
seeing if a branch is already checked out in die_if_checked_out().
To determine if a worktree is "current" is_current_worktree() compares
the gitdir of the worktree to the gitdir of "the_repository"
and returns true when they match. To get the gitdir of the
worktree it calls get_workree_git_dir() which also depends on
"the_repository". This means that even if "wt->path" matches
"wt->repo->worktree" is_current_worktree(wt) will return false when
"wt->repo" is not "the_repository". Consequently die_if_checked_out()
will fail to skip such a worktree when checking if a branch is already
checked out and may die errounously. Fix this by using the worktree's
repository instance instead of "the_repository" when comparing gitdirs.
The use of "the_repository" in is_current_wortree() comes from
replacing get_git_dir() with repo_get_git_dir() in 246deeac95
(environment: make `get_git_dir()` accept a repository, 2024-09-12). In
get_worktree_git_dir() it comes from replacing git_common_path() with
repo_common_path() in 07242c2a5a (path: drop `git_common_path()`
in favor of `repo_common_path()`, 2025-02-07). In both cases the
replacements appear to have been mechanical.
