262b04fa8d verify-pack -v: do not report "chain length 0"
When making a histogram of delta chain length in the pack, the program
collects number of objects whose delta depth exceeds the MAX_CHAIN limit
in histogram[0], and showed it as the number of items that exceeds the
limit correctly.  HOWEVER, it also showed the same number labeled as
"chain length = 0".

In fact, we are not showing the number of objects whose chain length is
zero, i.e. the base objects.  Correct this.

0fcb2caf29 am: allow individual e-mail files as input
We traditionally allowed a mbox file or a directory name of a maildir (but
never an individual file inside a maildir) to be given to "git am".  Even
though an individual file in a maildir (or more generally, a piece of
RFC2822 e-mail) is not a mbox file, it contains enough information to
create a commit out of it, so there is no reason to reject one.  Running
mailsplit on such a file feels stupid, but it does not hurt.

This builds on top of a5a6755 (git-am foreign patch support: introduce
patch_format, 2009-05-27) that introduced mailbox format detection.  The
codepath to deal with a mbox requires it to begin with "From " line and
also allows it to begin with "From: ", but a random piece of e-mail can
and often do begin with any valid RFC2822 header lines.

Instead of checking the first line, we extract all the lines up to the
first empty line, and make sure they look like e-mail headers.

A test is added to t4150 to demonstrate this feature.

5d5210c35a block-sha1: get rid of redundant 'lenW' context
.. and simplify the ctx->size logic.

We now count the size in bytes, which means that 'lenW' was always just
the low 6 bits of the total size, so we don't carry it around separately
any more.  And we do the 'size in bits' shift at the end.

e869e113c8 block-sha1: Use '(B&C)+(D&(B^C))' instead of '(B&C)|(D&(B|C))' in round 3
It's an equivalent expression, but the '+' gives us some freedom in
instruction selection (for example, we can use 'lea' rather than 'add'),
and associates with the other additions around it to give some minor

7b5075fcfb block-sha1: re-use the temporary array as we calculate the SHA1
The mozilla-SHA1 code did this 80-word array for the 80 iterations.  But
the SHA1 state is really just 512 bits, and you can actually keep it in
a kind of "circular queue" of just 16 words instead.

This requires us to do the xor updates as we go along (rather than as a
pre-phase), but that's really what we want to do anyway.

This gets me really close to the OpenSSL performance on my Nehalem.
Look ma, all C code (ok, there's the rol/ror hack, but that one doesn't
strictly even matter on my Nehalem, it's just a local optimization).

d68dc34cb4 git-describe: Die early if there are no possible descriptions
If we find no refs that may be used for git-describe with the current
options, then die early instead of pointlessly walking the whole
history.

In git.git with all the tags dropped, this makes "git describe" go down
from 0.244 to 0.003 seconds for me. This is especially noticeable with
"git submodule status" which calls describe with increasing levels of
allowed refs to be matched. For a submodule without tags, this means
that it walks the whole history in the submodule twice (first annotated,
then plain tags), just to find out that it can't describe the commit
anyway.

1a3d834f06 git-rev-list.txt: Clarify the use of multiple revision arguments
If one thinks of a revision as the set of commits which can be reached
from the rev, and of ^rev as the complement, then multiple arguments to
git rev-list can be neither understood as the intersection nor the union
of the individual sets.

But set language is the natural as well as logical language in which to
phrase this. So, add a paragraph which explains multiple arguments using
set language.

5749b0b2f9 don't let the delta cache grow unbounded in 'git repack'
I have 4GB of RAM on my system which should, in theory, be quite enough
to repack a 600 MB repository.  However the unbounded delta cache size
always pushes it into swap, at which point everything virtually comes to
a halt.  So unbounded caches are never a good idea.

A default of 256MB should be a good compromize between memory usage and
speed where medium sized repositories are still likely to fit in the
cache with a reasonable memory usage, and larger repositories are going
to take quite some time to repack already anyway.

While at it, clarify the associated config variable documentation
entries a bit.

c2ca1d79db Allow mailsplit (and hence git-am) to handle mails with CRLF line-endings
It is not that uncommon to have mails with DOS line-ending, notably
Thunderbird and web mailers like Gmail (when saving what they call
"original" message).  So modify mailsplit to convert CRLF line-endings to
just LF.

Since git-rebase is built on top of git-am, add an option to mailsplit to
be used by git-am when it is acting on behalf of git-rebase, to refrain
from doing this conversion.

And add a test to make sure that rebase still works.
