The path of the file to be locked is held in lock_file::filename,
which is a fixed-length buffer of length PATH_MAX. This buffer is
also (temporarily) used to hold the path of the lock file, which is
the path of the file being locked plus ".lock". Because of this, the
path of the file being locked must be less than (PATH_MAX - 5)
characters long (5 chars are needed for ".lock" and one character for
the NUL terminator).
On entry into lock_file(), the path length was only verified to be
less than PATH_MAX characters, not less than (PATH_MAX - 5)
characters.
When and if resolve_symlink() is called, then that function is
correctly told to treat the buffer as (PATH_MAX - 5) characters long.
This part is correct. However:
* If LOCK_NODEREF was specified, then resolve_symlink() is never
called.
* If resolve_symlink() is called but the path is not a symlink, then
the length check is never applied.
So it is possible for a path with length (PATH_MAX - 5 <= len <
PATH_MAX) to make it through the checks. When ".lock" is strcat()ted
to such a path, the lock_file::filename buffer is overflowed.
Fix the problem by adding a check when entering lock_file() that the
original path is less than (PATH_MAX - 5) characters.

One test in t1512 that expects a failure incorrectly passed. The
test prepares a commit whose object name begins with ten "0"s, and
also prepares a tag that points at the commit. The object name of
the tag also begins with ten "0"s. There is no other commit-ish
object in the repository whose name begins with such a prefix.
Ideally, in such a repository:
$ git rev-parse --verify 0000000000^{commit}
should yield that commit. If 0000000000 is taken as the commit
0000000000e4f, peeling it to a commmit yields that commit itself,
and if 0000000000 is taken as the tag 0000000000f8f, peeling it to a
commit also yields the same commit, so in that twisted sense, the
extended SHA-1 expression 0000000000^{commit} is unambigous. The
test that expects a failure is to check the above command.
The reason the test expects a failure is that we did not implement
such a "unification" of two candidate objects. What we did (or at
least, meant to) implement was to recognise that a commit-ish is
required to expand 0000000000, and notice that there are two succh
commit-ish, and diagnose the request as ambiguous.
However, there was a bug in the logic to check the candidate
objects. When the code saw 0000000000f8f (a tag) that shared the
shortened prefix (ten "0"s), it tried to make sure that the tag is a
commit-ish by looking at the tag object. Because it incorrectly
used lookup_object() when the tag has not been parsed, however, we
incorrectly declared that the tag is _not_ a commit-ish, leaving the
sole commit in the repository, 0000000000e4f, that has the required
prefix as "unique match", causing the test to pass when it shouldn't.
This fixes the logic to inspect the type of the object a tag refers
to, to make the test that is expected to fail correctly fail.

The earliest iteration of this test script used a magic string
110282 as the common prefix for ambiguous object names, but the
final edition switched the common prefix to 0000000000 (10 "0"s).

comments and a few tests. Replace them with the correct constants.

"stash save" is about saving the local change to the working tree,
but also about restoring the state of the last commit to the working
tree. When a local change is to turn a non-directory to a directory,
in order to restore the non-directory, everything in the directory
needs to be removed.
Which is fine when running "git stash save --include-untracked",
but without that option, untracked, newly created files in the
directory will have to be discarded, if the state you are restoring
to has a non-directory at the same path as the directory.
Introduce a safety valve to fail the operation in such case, using
the "ls-files --killed" which was designed for this exact purpose.
The "stash save" is stopped when untracked files need to be
discarded because their leading path ceased to be a directory, and
the user is required to pass --force to really have the data
removed.

When the working tree walker encounters a directory, it asks the
function treat_directory() if it should descend into it, show it as
an untracked directory, or do something else. When the directory is
the top of the submodule working tree, we used to say "That is an
untracked directory", which was bogus.
It is an entity that is tracked in the index of the repository we
are looking at, and that is not to be descended into it. Return
path_none, not path_untracked, to report that.
The existing case that path_untracked is returned for a newly
discovered submodule that is not tracked in the index (this only
happens when DIR_NO_GITLINKS option is not used) is unchanged, but
that is exactly because the submodule is not tracked in the index.
