Usually when applying a binary diff generated without
--binary, it will be rejected early, as we don't even have
the full sha1 of the pre- and post-images.
However, if the diff is generated with --full-index (but not
--binary), then we will actually try to apply it. If we have
the postimage blob, then we can take a shortcut and never
even look at the binary diff at all (e.g., this can happen
when rebasing changes within a repository).
If we don't have the postimage blob, though, we try to look
at the actual fragments, of which there are none, and get a
segfault. This patch checks explicitly for that case and
complains to the user instead of segfaulting. We need to
keep the check at a low level so that the "shortcut" case
above continues to work.
We also add a test that demonstrates the segfault. While
we're at it, let's also explicitly test the shortcut case.

Since b541248 (merge.conflictstyle: choose between "merge" and "diff3
-m" styles, 2008-08-29), git-merge-file uses setup_directory_gently(),
thus cd'ing around to find any possible config files to use.
This broke merge-file when it is called from within a subdirectory of
a repository, and the arguments are all relative paths.
Fix by prepending the prefix, as passed down from the main git
setup code, if there is any.

commit-tree: free commit message before exiting
The code paths for showing commits in "git log" and "git
rev-list --graph" correctly handle embedded NULs by looking
only at the resulting strbuf's length, and never treating it
as a C string. The code path for regular rev-list, however,
used printf("%s"), which resulted in truncated output. This
patch uses fwrite instead, like the --graph code path.

The buffer used to construct paths like ".git/objects/info" and
".git/objects/pack" is allocated on the heap and never freed.
So free it. While at it, factor out the relevant code into its own
function and rename the sha1_dir variable to object_directory (to
match the change in everyday usage after the renaming of
SHA1_FILE_DIRECTORY in v0.99~603^2~7, 2005).

cherry-pick will segfault when transplanting a root commit if the --ff
option is used. This happens because the "parent" pointer is set to NULL
when the commit being cherry-picked has no parents. Later, when "parent"
is dereferenced, the cherry-pick segfaults.
Fix this by checking whether "parent" is NULL before dereferencing it and
add a test for this case of cherry-picking a root commit with --ff.

Currently, read-tree can be run without tree-ish arguments, in which
case it will empty the index. Since this behavior is undocumented and
perhaps a bit too invasive to be the "default" action for read-tree,
deprecate it in favor of a new --empty option that does the same thing.

Give "shortlog_len" parameter to the fmt_merge_msg(), remove its
"merge_summary" parameter, and remove fmt_merge_msg_shortlog() function.
In the updated API, shortlog_len == 0 means no shortlog is given.
The parameter "merge_title" controls if the title of the merge commit is
autogenerated (it reads something like "Merge branch ..."), and typically
it is set to true when the caller does not give its own message.

builtin/fetch.c: ignore merge config when not fetching from branch's remote

t9350 sets up a commit where a file is both copied and renamed. The output
of fast-export for this commit should look like this:
author ...
committer ...
from :19
C "file2" "file4"
R "file2" "file5"
The order of the two modification lines is derived from the result that
the diff machinery produces.
060df62 (fast-export: Fix output order of D/F changes) inserted a qsort
call that modifies the order of the diff result. Unfortunately, qsort need
not be stable. Therefore, it is possible that the 'R' line appears before
the 'C' line and the resulting fast-import stream is incorrect.
Fix it by forcing that the rename entry is printed after all other
modification lines with the same file name.
