Add testcases that cover three failures with current git merge, all
involving renaming one file on both sides of history:
Case 1:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. Adding a new file on one of those
sides of history whose name happens to match the rename source should not
cause the merge to suddenly succeed.
Case 2:
If a single file is renamed on both sides of history but renamed
identically, there should not be a conflict. This works fine. However,
if one of those sides also added a new file that happened to match the
rename source, then that file should be left alone. Currently, the
rename/rename conflict handling causes that new file to become untracked.
Case 3:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. This works currently. However,
if those renames also involve rename/add conflicts (i.e. there are new
files on one side of history that match the destination of the rename of
the other side of history), then the resulting conflict should be recorded
in the index, showing that there were multiple files with a given filename.
Currently, git silently discards one of file versions.

rename/rename conflicts, both with one file being renamed to two different
files and with two files being renamed to the same file, should leave the
index and the working copy in a sane state with appropriate conflict
recording, auxiliary files, etc. Git seems to handle one of the two cases
alright, but has some problems with the two files being renamed to one
case. Add tests for both cases.

Add testcases that cover a variety of merge issues with files being
renamed and modified on different sides of history, when there are
directories possibly conflicting with the rename location.
Case 1:
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a non-conflicting
way but is renamed to the location of the new directory.
Case 2:
[Same as case 1, but there is also a content conflict. In detail:]
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a conflicting way
and it is renamed to the location of the new directory.
Case 3:
[Similar to case 1, but the "conflicting" directory is the directory
where the file original resided. In detail:]
On one side of history, a file is modified. On the other side of history,
the file is modified in a non-conflicting way, but the directory it was
under is removed and the file is renamed to the location of the directory
it used to reside in (i.e. 'sub/file' gets renamed to 'sub'). This is
flagged as a directory/rename conflict, but should be able to be resolved
since the directory can be cleanly removed by the merge.
One branch renames a file and makes a file where the directory the renamed
file used to be in, and the other branch updates the file in
place. Merging them should resolve it cleanly as long as the content level
change on the branches do not overlap and rename is detected, or should
leave conflict without losing information.

If there is a cleanly resolvable rename/modify conflict AND there is a new
file introduced on the renamed side of the merge whose name happens to
match that of the source of the rename (but is otherwise unrelated to the
rename), then git fails to cleanly resolve the merge despite the fact that
the new file should not cause any problems.

The handle_options() function advances the base of the argument array and
returns the number of arguments it used. The caller in handle_alias()
wants to reallocate the argv array it passes to this function, and
attempts to do so by subtracting the returned value to compensate for the
change handle_options() makes to the new_argv.
But handle_options() did not correctly count when "-c <config=value>" is
given, causing a wrong pointer to be passed to realloc().
Fix it by saving the original argv at the beginning of handle_options(),
and return the difference between the final value of argv, which will
relieve the places that move the array pointer from the additional burden
of keeping track of "handled" counter.

Previously we parsed GIT_CONFIG_PARAMETERS lazily into a
linked list, and then checked that list during future
invocations of git_config. However, that ignores the fact
that the environment variable could change during our run
(e.g., because we parse more "-c" as part of an alias).
Instead, let's just re-parse the environment variable each
time. It's generally not very big, and it's no more work
than parsing the config files, anyway.
As a bonus, we can ditch all of the linked list storage code
entirely, making the code much simpler.
The test unfortunately still does not pass because of an
unrelated bug in handle_options.

With diff.suppress-blank-empty=true, "git diff --word-diff" would
output data that had been read from uninitialized heap memory.
The problem was that fn_out_consume did not account for the
possibility of a line with length 1, i.e., the empty context line
that diff.suppress-blank-empty=true converts from " \n" to "\n".
Since it assumed there would always be a prefix character (the space),
it decremented "len" unconditionally, thus passing len=0 to emit_line,
which would then blindly call emit_line_0 with len=-1 which would
pass that value on to fwrite as SIZE_MAX. Boom.

When the command line has "--" disambiguator, we take the remainder of

we need to append to the existing prune_data and end up attempting to
realloc(3) it. That would not work.

processing. Also avoid counting the number of existing paths in the

Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh. Modern POSIX compliant shells (e.g. dash,
ksh, bash) all seem to interpret POSIX "2.6.2 Parameter Expansion" that
says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group. We can avoid this issue and future-proof the
test by a slight rewrite.

The parsing of the additional command line parameters supplied to
the branch.<name>.mergeoptions configuration variable was implemented
at the wrong stage. If any merge-related variable came after we read
branch.<name>.mergeoptions, the earlier value was overwritten.
We should first read all the merge.* configuration, override them by
reading from branch.<name>.mergeoptions and then finally read from
the command line.
This patch should fix it, even though I now strongly suspect that
branch.<name>.mergeoptions that gives a single command line that
needs to be parsed was likely to be an ill-conceived idea to begin
with. Sigh...
