The difftool dir-diff mode handles symlinks by replacing them with their
readlink(2) values. This allows diff tools to see changes to symlinks
as if they were regular text diffs with the old and new path values.
This is analogous to what "git diff" displays when symlinks change.
The temporary diff directories that are created initially contain
symlinks because they get checked-out using a temporary index that
retains the original symlinks as checked-in to the repository.
A bug was introduced when difftool was rewritten in C that made
difftool write the readlink(2) contents into the pointed-to file rather
than the symlink itself. The write was going through the symlink and
writing to its target rather than writing to the symlink path itself.
Replace symlinks with raw text files by unlinking the symlink path
before writing the readlink(2) content into them.
When 18ec800512 (difftool: handle modified symlinks in dir-diff mode,
2017-03-15) added handling for modified symlinks this bug got recorded
in the test suite. The tests included the pointed-to symlink target
paths. These paths were being reported because difftool was erroneously
writing to them, but they should have never been reported nor written.
Correct the modified-symlinks test cases by removing the target files
from the expected output.
Add a test to ensure that symlinks are written with the readlink(2)
values and that the target files contain their original content.

When cloning a repository with an unborn HEAD, we'll set the local HEAD
to match it only if the local repository is non-bare. This is
inconsistent with all other combinations:
remote HEAD | local repo | local HEAD
-----------------------------------------------
points to commit | non-bare | same as remote
points to commit | bare | same as remote
unborn | non-bare | same as remote
unborn | bare | local default
So I don't think this is some clever or subtle behavior, but just a bug
in 4f37d45706 (clone: respect remote unborn HEAD, 2021-02-05). And it's
easy to see how we ended up there. Before that commit, the code to set
up the HEAD for an empty repo was guarded by "if (!option_bare)". That's
because the only thing it did was call install_branch_config(), and we
don't want to do so for a bare repository (unborn HEAD or not).
That commit put the handling of unborn HEADs into the same block, since
those also need to call install_branch_config(). But the unborn case has
an additional side effect of calling create_symref(), and we want that
to happen whether we are bare or not.
This patch just pulls all of the "figure out the default branch" code
out of the "!option_bare" block. Only the actual config installation is
kept there.
Note that this does mean we might allocate "ref" and not use it (if the
remote is empty but did not advertise an unborn HEAD). But that's not
really a big deal since this isn't a hot code path, and it keeps the
code simple. The alternative would be handling unborn_head_target
separately, but that gets confusing since its memory ownership is
tangled up with the "ref" variable.
There's just one new test, for the case we're fixing. The other ones in
the table are handled elsewhere (the unborn non-bare case just above,
and the actually-born cases in t5601, t5606, and t5609, as they do not
require v2's "unborn" protocol extension).

We currently store each submodule gitdir in ".git/modules/<name>", but
this has problems with some submodule naming schemes, as described in a
comment in submodule_name_to_gitdir() in this patch.
Extract the determination of the location of a submodule's gitdir into
its own function submodule_name_to_gitdir(). For now, the problem
remains unsolved, but this puts us in a better position for finding a
solution.
This was motivated, at $DAYJOB, by a part of Android's repo hierarchy
[1]. In particular, there is a repo "build", and several repos of the
form "build/<name>".
This is based on earlier work by Brandon Williams [2].

We check that git.html exists, regardless of the page the user wants to open.
Checking whether the requested page exists instead gives us a smoother user
experience in two use cases:
1) The requested page doesn't exist
When calling a git command and there is an error, most users reasonably expect
git to produce an error message on the standard error stream, but in this case
we pass the filepath to git web--browse which passes it on to a browser (or a
helper program like xdg-open or start that should in turn open a browser)
without any error and many GUI based browsers or helpers won't output such a
message onto the standard error stream.
Especially the helper programs tend to show the corresponding error message in
a message box and wait for user input before exiting. This leaves users in
interactive console sessions without an error message in their console,
without a console prompt and without the help page they expected.
2) git.html is missing for some reason, but the user asked for some other page
We currently refuse to show any local html help page when we can't find
git.html. Even if the requested help page exists. If we check for the requested
page instead, we can show the user all available pages and only error out on
those that don't exist.

As was noted in 1a85b49b87 (parse-options: make OPT_ARGUMENT() more
useful, 2019-03-14) there's only ever been one user of the
OPT_ARGUMENT(), that user was added in 20de316e33 (difftool: allow
running outside Git worktrees with --no-index, 2019-03-14).
The OPT_ARGUMENT() feature itself was added way back in
580d5bffde (parse-options: new option type to treat an option-like
parameter as an argument., 2008-03-02), but as discussed in
1a85b49b87 wasn't used until 20de316e33 in 2019.
Now that the preceding commit has migrated this code over to using
"struct strvec" to manage the "args" member of a "struct
child_process", we can just use that directly instead of relying on
OPT_ARGUMENT.
This has a minor change in behavior in that if we'll pass --no-index
we'll now always pass it as the first argument, before we'd pass it in
whatever position the caller did. Preserving this was the real value
of OPT_ARGUMENT(), but as it turns out we didn't need that either. We
can always inject it as the first argument, the other end will parse
it just the same.
Note that we cannot remove the "out" and "cpidx" members of "struct
parse_opt_ctx_t" added in 580d5bffde, while they were introduced with
OPT_ARGUMENT() we since used them for other things.

When the launchctl_boot_plist() function was added in
a16eb6b1ff (maintenance: skip bootout/bootstrap when plist is
registered, 2021-08-24), an unused call to launchctl_get_uid() was
added along with it. That call appears to have been copy/pasted from
launchctl_boot_plist().
Since we can remove that, we can also get rid of the "result"
variable, whose only purpose was allow for the free() between its
assignment and the return. That pattern also appears to have been
copy/pasted from launchctl_boot_plist().
As the patch shows the returned value from launchctl_get_uid() wasn't
used at all in this function. The launchctl_get_uid() function itself
just calls xstrfmt() and getuid(), neither of which have any subtle
global side-effects, so this removal is safe.

If a user deletes a file and places a directory of untracked files
there, then stashes all these changes, the untracked directory of files
cannot be restored until after the corresponding file in the way is
removed. So, restore changes to tracked files before restoring
untracked files.
There is no counterpart problem to worry about with the user deleting an
untracked file and then add a tracked one in its place. Git does not
track untracked files, and so will not know the untracked file was
deleted, and thus won't be able to stash the removal of that file.

When a file is removed from the cache, but there is a file of the same
name present in the working directory, we would normally treat that file
in the working directory as untracked. However, in the case of stash,
doing that would prevent a simple 'git stash push', because the untracked
file would be in the way of restoring the deleted file.
git stash, however, blindly assumes that whatever is in the working
directory for a deleted file is wanted and passes that path along to
update-index. That causes problems when the working directory contains
a directory with the same name as the deleted file. Add some code for
this special case that will avoid passing directory names to
update-index.
