This adds "binary patch" to the diff output and teaches apply
what to do with them.
On the diff generation side, traditionally, we said "Binary
files differ\n" without giving anything other than the preimage
and postimage object name on the index line. This was good
enough for applying a patch generated from your own repository
(very useful while rebasing), because the postimage would be
available in such a case. However, this was not useful when the
recipient of such a patch via e-mail were to apply it, even if
the preimage was available.
This patch allows the diff to generate "binary" patch when
operating under --full-index option. The binary patch follows
the usual extended git diff headers, and looks like this:
"GIT binary patch\n"
<length byte><data>"\n"
...
"\n"
Each line is prefixed with a "length-byte", whose value is upper
or lowercase alphabet that encodes number of bytes that the data
on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ...,
'Z' means 26, 'a' means 27, ...). <data> is 1 or more groups of
5-byte sequence, each of which encodes up to 4 bytes in base85
encoding. Because 52 / 4 * 5 = 65 and we have the length byte,
an output line is capped to 66 characters. The payload is the
same diff-delta as we use in the packfiles.
On the consumption side, git-apply now can decode and apply the
binary patch when --allow-binary-replacement is given, the diff
was generated with --full-index, and the receiving repository
has the preimage blob, which is the same condition as it always
required when accepting an "Binary files differ\n" patch.

One of my post-update scripts runs a git-fetch into a separate
repository and sends the results back to me (2>&1); I end up
getting this in the mail:
Generating pack...
Done counting 180 objects.
Result has 131 objects.
Deltifying 131 objects.
0% (0/131) done^M 1% (2/131) done^M...
This defaults not to do the progress report when not on a tty.
You could give --progress to force the progress report, but
let's not bother even documenting it nor mentioning it in the
usage string.

When called with "--stdout", it still writes to standard output.
Notable differences to git-format-patch:
- since fmt-patch uses the standardized logging machinery, it is
no longer "From nobody", but "From <commit_sha1>",
- the empty lines before and after the "---" just before the
diffstat are no longer there,
- git-format-patch outputs the commit_sha1 just before the first
diff, which fmt-patch does not,
- the file names are no longer output to stdout, but to stderr
(since stdout is freopen()ed all the time), and
- "git fmt-patch HEAD^" does not work as expected: it outputs
*all* commits reachable from HEAD^!
The last one is possibly a showstopper. At least I used to call that
command quite often...

Somebody on the #git channel complained that the sha1_to_hex() thing uses
a static buffer which caused an error message to show the same hex output
twice instead of showing two different ones.
That's pretty easily rectified by making it uses a simple LRU of a few
buffers, which also allows some other users (that were aware of the buffer
re-use) to be written in a more straightforward manner.

It is useless to preserve multiple hash entries for consecutive blocks
with the same hash. Keeping only the first one will allow for matching
the longest string of identical bytes while subsequent blocks will only
allow for shorter matches. The backward matching code will match the
end of it as necessary.
This improves both performances (no repeated string compare with long
successions of identical bytes, or even small group of bytes), as well
as compression (less likely to need random hash bucket entry culling),
especially with sparse files.
With well behaved data sets this patch doesn't change much.
