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.

Suggested by Nicolas Pitre and linux@horizon.com.

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
scheduling freedom.

Avoid repeating the shared parts of the different rounds by adding a

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).

b8e48a89b8 block-sha1: try to use rol/ror appropriately
Use the one with the smaller constant.  It _can_ generate slightly
smaller code (a constant of 1 is special), but perhaps more importantly
it's possibly faster on any uarch that does a rotate with a loop.

d7c208a92e Add new optimized C 'block-sha1' routines
Based on the mozilla SHA1 routine, but doing the input data accesses a
word at a time and with 'htonl()' instead of loading bytes and shifting.

It requires an architecture that is ok with unaligned 32-bit loads and a

Currently, the documentation suggests that 'git merge-base -a' and 'git
show-branch --merge-base' are equivalent (in fact it claims that the
former cannot handle more than two revs).

Alas, the handling of more than two revs is very different. Document
this by tests and correct the documentation to reflect this.

2da846e709 Documentation: git-send-email: correct statement about standard ports
The current documentation states that servers typically listen on port
465 and calls this "ssmtp". While it's true that many mail servers use
port 465 for SSL smtp, this is non-standard, and hails from the days
before smtp and submission TLS support, that arrived in RFC2487 and
RFC3207. Port 465 is actually assigned by IANA for unrelated purposes,
and is mostly still used by mail servers today only to support Outlook
Express.

In any case, this patch helps the documentation better reflect both
standards and reality, while still helpfully mentioning ports numbers
that a user may wish to specify.

ebdaae372b config: Keep inner whitespace verbatim
Configuration values are expected to be quoted when they have leading or
trailing whitespace, but inner whitespace should be kept verbatim even if
the value is not quoted. This is already documented in git-config(1), but
the code caused inner whitespace to be collapsed to a single space,
breaking, for example, clones from a path that has two consecutive spaces
in it, as future fetches would only see a single space.

79559f27be git fast-export: add --no-data option
When using git fast-export and git fast-import to rewrite the history
of a repository with large binary files, almost all of the time is
spent dealing with blobs.  This is extremely inefficient if all we want
to do is rewrite the commits and tree structure.  --no-data skips the
output of blobs and writes SHA-1s instead of marks, which provides a
massive speedup.

The problem is that if a file was replaced with a directory containing
another file with the same content and mode, an attempt to merge it
with a branch descended from a commit before this F->D transition will
