Even if there is an empty directory where we look for the loose version
of a reference, check for a packed reference before giving up. This
fixes the failing test that was introduced two commits ago.

Add some tests checking that it is possible to work with a reference
even if there is an empty directory where the loose ref would be stored.
One of the new tests demonstrates a bug that has been with us since at
least 2.5.0--single reference lookup gives up when it sees the
directory, even if the reference exists as a packed ref. This probably
hasn't been reported before because Git usually cleans up empty
directories when packing references.
This bug will be fixed shortly.

With one exception, we require the index to exactly match the
current HEAD commit at the time git merge is invoked. This
expectation was even documented in git-merge.txt until commit
ebef7e5 (Documentation: simplify How Merge Works, 2010-01-23).
Most merge strategies enforced this requirement, but it turns out
not all did. The current exceptions were the following two:
* ff updates
* octopus merges
ff updates actually will error out if the staged change is to a path
modified between HEAD and the commit being merged. If the path(s)
that are staged are files unrelated to the changes between these two
commits, though, then an ff update will just keep these staged
changes around after the merge. This is the one exception we
expected to the abort-merge-if- index-doesn't-match-HEAD rule.
For octopus merges, the rule should be enforced. Unfortunately, the
current behavior of the code is to ignore the difference and use the
staged changes in place of whatever is in HEAD as it proceeds to
perform the merge. So if the staged changes can be cleanly merged
with all the other heads, then the staged changes will just be
incorported into the resulting commit. If the staged changes cannot
be cleanly merged with all the other heads, the merge is not aborted
-- merge conflicts are simply reported as if HEAD had originally
contained whatever the index did.
Add testcases that check our expectations. A subsequent commit will
correct the erroneous octopus merge behavior.

If read_tree_trivial() succeeds and produces a tree that is already
in the object store, then the index is not written to disk, leaving
it out-of-sync with both HEAD and the working tree.
In order to write the index back out to disk after a merge,
write_index_locked() needs to be called. For most merge strategies, this
is done from try_merge_strategy(). For fast forward updates, this is
done from checkout_fast_forward(). When trivial merges work, the call to
write_index_locked() is buried a little deeper:
merge_trivial()
-> write_tree_trivial()
-> write_cache_as_tree()
-> write_index_as_tree()
-> write_locked_index()
However, it is only called when !cache_tree_fully_valid(), which is how
this bug is triggered. But that also shows why this bug doesn't affect
any other merge strategies or cases.
Add a direct call to write_index_locked() from merge_trivial() to fix
this issue. Since the indirect call to write_locked_index() was
conditional on cache_tree_fully_valid(), it won't be written twice.

Repeating a trivial merge more than once will leave the index out of
sync, despite being clean before the merge and operating on the
exact same heads as the first run. The recorded merge has the
correct tree and the working tree is brought up to date, it is just
the index that is left as it was before the merge. Every attempt to
repeat the merge beyond the first will leave the index in the same
weird out-of-sync state.

The test uses hardcoded #!/bin/sh to create a pre-commit hook
script. Because the generated script uses $(command substitution),
which is not supported by /bin/sh on some platforms (e.g. Solaris),
the resulting pre-commit always fails.
Which is not noticeable as the test that uses the hook is about
checking the behaviour of the command when the hook fails ;-), but
nevertheless it is not testing what we wanted to test.
Use write_script so that the resulting script is run under the same
shell our scripted Porcelain commands are run, which must support
the necessary $(construct).

The test prepares a sample file "dir/two" with a single incomplete
line in it with "printf", and also prepares a small helper script
"diff" to create a file with a single incomplete line in it, again
with "printf". The output from the latter is compared with an
expected output, again prepared with "printf" hence lacking the
final LF. There is no reason for this test to be using files with
an incomplete line at the end, and these look more like a mistake
of not using
printf "%s\n" "string to be written"
and using
printf "string to be written"
Depending on what would be in $GIT_PREFIX, using the latter form
could be a bug waiting to happen. Correct them.
Also, the test uses hardcoded #!/bin/sh to create a small helper
script. For a small task like what the generated script does, it
does not matter too much in that what appears as /bin/sh would not
be _so_ broken, but while we are at it, use write_script instead,
which happens to make the result easier to read by reducing need
of one level of quoting.

The recent cleanup in b7cbbff switched t5532's use of
backticks to $(). This matches our normal shell style, which
is good. But it also breaks the test on Solaris, where
/bin/sh does not understand $().
Our normal shell style assumes a modern-ish shell which
knows about $(). However, some tests create small helper
scripts and just write "#!/bin/sh" into them. These scripts
either need to go back to using backticks, or they need to
respect $SHELL_PATH. The easiest way to do the latter is to
use write_script.
While we're at it, let's also stick the script creation
inside a test_expect block (our usual style), and split the
perl snippet into its own script (to prevent quoting
madness).

"git merge" used to allow merging two branches that have no common
base by default, which led to a brand new history of an existing
project created and then get pulled by an unsuspecting maintainer,
which allowed an unnecessary parallel history merged into the
existing project. The command has been taught not to allow this by
default, with an escape hatch "--allow-unrelated-histories" option
to be used in a rare event that merges histories of two projects
that started their lives independently.

When f9568530 (builtin-commit: resurrect behavior for multiple -m
options, 2007-11-11) converted a "char *message" to "struct strbuf
message" to hold the messages given with the "-m" option, it
incorrectly changed the checks "did we get a message with the -m
option?" to "is message.len 0?". Later, we noticed one breakage
from this change and corrected it with 25206778 (commit: don't start
editor if empty message is given with -m, 2013-05-25).
However, "we got a message with -m, even though an empty one, so we
shouldn't be launching an editor" was not the only breakage.
* "git commit --amend -m '' --allow-empty", even though it looks
strange, is a valid request to amend the commit to have no
message at all. Due to the misdetection of the presence of -m on
the command line, we ended up keeping the log messsage from the
original commit.
* "git commit -m "$msg" -F file" should be rejected whether $msg is
an empty string or not, but due to the same bug, was not rejected
when $msg is empty.
* "git -c template=file -m "$msg"" should ignore the template even
when $msg is empty, but it didn't and instead used the contents
from the template file.
Correct these by checking have_option_m, which the earlier 25206778
introduced to fix the same bug.

Because conflicts with the same contents inside conflict blocks
enclosed by "<<<<<<<" and ">>>>>>>" can now have multiple variants
to help three-way merge to adjust to the differences outside the
conflict blocks, "rerere forget $path" needs to be taught that there
may be multiple recorded resolutions that share the same conflict
hash (which groups the conflicts with "the same contents inside
conflict blocks"), among which there are some that would not be
relevant to the conflict we are looking at. These "other variants"
that happen to share the same conflict hash should not be cleared,
and the variant that would apply to the current conflict may not be
the zero-th one (which is the only one that is cleared by the
current code).
After finding the conflict hash, iterate over the existing variants
and try to resolve the conflict using each of them to find the one
that "cleanly" resolves the current conflict. That is the one we
want to forget and record the preimage for, so that the user can
record the corrected resolution.

Commit aedcb7d (branch.c: use 'ref-filter' APIs, 2015-09-23)
adjusted the symref-printing code to look like this:
if (item->symref) {
skip_prefix(item->symref, "refs/remotes/", &desc);
strbuf_addf(&out, " -> %s", desc);
}
This has three bugs in it:
1. It always skips past "refs/remotes/", instead of
skipping past the prefix associated with the branch we
are showing (so commonly we see "refs/remotes/" for the
refs/remotes/origin/HEAD symref, but the previous code
would skip "refs/heads/" when showing a symref it found
in refs/heads/.
2. If skip_prefix() does not match, it leaves "desc"
untouched, and we show whatever happened to be in it
(which is the refname from a call to skip_prefix()
earlier in the function).
3. If we do match with skip_prefix(), we stomp on the
"desc" variable, which is later passed to
add_verbose_info(). We probably want to retain the
original refname there (though it likely doesn't matter
in practice, since after all, one points to the other).
The fix to match the original code is fairly easy: record
the prefix to strip based on item->kind, and use it here.
However, since we already have a local variable named "prefix",
let's give the two prefixes verbose names so we don't
confuse them.
