When a commit changes a path P that used to be a file to a directory
and creates a new path P/X in it, "git show" would say that file P
was removed and file P/X was created for such a commit.
However, if we compare two directories, D1 and D2, where D1 has a
file D1/P in it and D2 has a directory D2/P under which there is a
file D2/P/X, and ask "git diff --no-index D1 D2" to show their
differences, we simply get a refusal "file/directory conflict".
Surely, that may be what GNU diff does, but we can do better and it
is easy to do so.

"git diff --no-index" was supposed to be a poor-man's approach to
allow using Git diff goodies outside of a Git repository, without
having to patch mainstream diff implementations.
Unlike a POSIX diff that treats "diff D F" (or "diff F D") as a
request to compare D/F and F (or F and D/F) when D is a directory
and F is a file, however, we did not accept such a command line and
instead barfed with "file/directory conflict".
Imitate what POSIX diff does and append the basename of the file
after the name of the directory before comparing.

The run-command interface was easy to abuse and make a pipe for us

attempt to read its output, which is a pattern that lead to a

The idea of this helper is that we want to save the current
value of a config variable and then restore it again after
the test completes. However, there's no point in actually
saving the value; it should always be restored to the string
"never" (which you can confirm by instrumenting
save_confirm to print the value it finds).
Let's just replace it with a single test_when_finished call.

Since shell loops may drop the exit code of failed commands
inside the loop, some tests try to keep track of the status
by setting a variable. This can end up cumbersome and hard

function or inside a test snippet).

These are all cases where we do a setup step of the form:
for i in $foo; do
set_up $i || break
done &&
more_setup
would not notice a failure in set_up (because break always
returns a 0 exit code). These are just setup steps that we
do not expect to fail, but it does not hurt to be defensive.
Most can be fixed by converting the "break" to a "return 1"
(since we eval our tests inside a function for just this
purpose). A few of the loops are inside subshells, so we can
use just "exit 1" to break out of the subshell. And a few
can actually be made shorter by just unrolling the loop.

When checking a list of file mtimes, we use a loop and break
out early from the loop if any entry does not match.
However, the exit code of a loop exited via break is always
0, meaning that the test will fail to notice we had a
mismatch. Since the loop is inside a function, we can fix
this by doing an early "return 1".

When we test deleting notes, we run "git notes remove" in a
loop. However, the exit value of the loop will only reflect
the final note we process. We should break out of the loop
with a failing exit code as soon as we see a problem.
Note that we can call "exit 1" here without explicitly
creating a subshell, because the while loop on the
right-hand side of a pipe executes in its own implicit
subshell.
Note also that the "break" above does not suffer the same
problem; it is meant to exit the loop early at a certain
number of iterations. We can bump it into the conditional of
the loop to make this more obvious.

A loop like:
for f in one two; do
something $f ||
break
done
will correctly break out of the loop when we see a failure
of one item, but the resulting exit code will always be
zero. We can fix that by putting the loop into a function or
subshell, but in this case it is simpler still to just
unroll the loop. We do add a helper function, which
hopefully makes the end result even more readable (in
addition to being shorter).

When copying the test repository, we try to detect whether
the copy succeeded. However, most of the heavy lifting is
done inside a for loop, where our "break" will lose the exit

that we are in a subshell, and just "exit 1" to break out
with a code.

The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".
Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement. ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.
Move it to dir.c where match_pathspec() is defined.

t0302 now tests git-credential-store's support for the XDG user-specific
configuration file $XDG_CONFIG_HOME/git/credentials. Specifically:
* Ensure that the XDG file is strictly opt-in. It should not be created
by git at all times if it does not exist.
* Conversely, if the XDG file exists, ~/.git-credentials should
not be created at all times.
* If both the XDG file and ~/.git-credentials exists, then both files
should be used for credential lookups. However, credentials should
only be written to ~/.git-credentials.
* Credentials must be erased from both files.
* $XDG_CONFIG_HOME can be a custom directory set by the user as per the
XDG base directory specification. Test that git-credential-store
respects that, but defaults to "~/.config/git/credentials" if it does
not exist or is empty.

Add $XDG_CONFIG_HOME/git/credentials to the default credential search
path of git-credential-store. This allows git-credential-store to
support user-specific configuration files in accordance with the XDG
base directory specification[1].
[1] http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
~/.git-credentials has a higher precedence than
$XDG_CONFIG_HOME/git/credentials when looking up credentials. This
means that if any duplicate matching credentials are found in the xdg
file (due to ~/.git-credentials being updated by old versions of git or
outdated tools), they will not be used at all. This is to give the user
some leeway in switching to old versions of git while keeping the xdg
directory. This is consistent with the behavior of git-config.
However, the higher precedence of ~/.git-credentials means that as long
as ~/.git-credentials exist, all credentials will be written to the
~/.git-credentials file even if the user has an xdg file as having a
~/.git-credentials file indicates that the user wants to preserve
backwards-compatibility. This is also consistent with the behavior of
git-config.
To make this precedence explicit in docs/git-credential-store, add a new
section FILES that lists out the credential file paths in their order of
precedence, and explain how the ordering affects the lookup, storage and
erase operations.
Also, update the documentation for --file to briefly explain the
operations on multiple files if the --file option is not provided.
Since the xdg file will not be used unless it actually exists, to
prevent the situation where some credentials are present in the xdg file
while some are present in the home file, users are recommended to not
create the xdg file if they require compatibility with old versions of
git or outdated tools. Note, though, that "erase" can be used to
explicitly erase matching credentials from all files.

Previously, git-credential-store only supported storing credentials in a
single file: ~/.git-credentials. In order to support the XDG base
directory specification[1], git-credential-store needs to be able to
lookup and erase credentials from multiple files, as well as to pick the
appropriate file to write to so that the credentials can be found on
subsequent lookups.
[1] http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
Note that some credential storage files may not be owned, readable or
writable by the user, as they may be system-wide files that are meant to
apply to every user.
Instead of a single file path, lookup_credential(), remove_credential()
and store_credential() now take a precedence-ordered string_list of
file paths. lookup_credential() expects both user-specific and
system-wide credential files to be provided to support the use case of
system administrators setting default credentials for users.
remove_credential() and store_credential() expect only the user-specific
credential files to be provided as usually the only config files that
users are allowed to edit are their own user-specific ones.
lookup_credential() will read these (user-specific and system-wide) file
paths in order until it finds the 1st matching credential and print it.
As some files may be private and thus unreadable, any file which cannot
be read will be ignored silently.
remove_credential() will erase credentials from all (user-specific)
files in the list. This is because if credentials are only erased from
the file with the highest precedence, a matching credential may still be
found in a file further down the list. (Note that due to the lockfile
code, this requires the directory to be writable, which should be so for
user-specific config files)
store_credential() will write the credentials to the first existing
(user-specific) file in the list. If none of the files in the list
exist, store_credential() will write to the filename specified by the
first item of the filename list. For backwards compatibility, this
filename should be "~/.git-credentials".
