Import macro REPEAT_BYTE from Linux (arch/x86/include/asm/word-at-a-time.h)
to avoid 64-bit integer literals, which cause some 32-bit compilers to
print warnings.

Darwin does not define __WORDSIZE, and compiles the 32-bit code path
on 64-bit systems, resulting in a totally broken git.
I could not find an alternative -- other than the platform symbols
(__x86_64__ etc.) -- that does the test in the preprocessor. However,
we can also just test for the size of a 'long', which is what really
matters here. Any compiler worth its salt will leave only the branch
relevant for its platform, and indeed on Linux/GCC the numbers don't
change:

Redo the hashing loop in xdl_hash_record in a way that loads an entire
'long' at a time, using masking tricks to see when and where we found
the terminating '\n'.
I stole inspiration and code from the posts by Linus Torvalds around
https://lkml.org/lkml/2012/3/2/452https://lkml.org/lkml/2012/3/5/6
His method reads the buffers in sizeof(long) increments, and may thus
overrun it by at most sizeof(long)-1 bytes before it sees the final
newline (or hits the buffer length check). I considered padding out
all buffers by a suitable amount to "catch" the overrun, but
* this does not work for mmap()'d buffers: if you map 4096+8 bytes
from a 4096 byte file, accessing the last 8 bytes results in a
SIGBUS on my machine; and
* it would also be extremely ugly because it intrudes deep into the
unpacking machinery.
So I adapted it to not read beyond the buffer at all. Instead, it
reads the final partial word byte-by-byte and strings it together.
Then it can use the same logic as before to finish the hashing.
So far we enable this only on x86_64, where it provides nice speedup
for diff-related work:
Test origin/next tr/xdiff-fast-hash
-----------------------------------------------------------------------------
4000.1: log -3000 (baseline) 0.07(0.05+0.02) 0.08(0.06+0.02) +14.3%
4000.2: log --raw -3000 (tree-only) 0.37(0.33+0.04) 0.37(0.32+0.04) +0.0%
4000.3: log -p -3000 (Myers) 1.75(1.65+0.09) 1.60(1.49+0.10) -8.6%
4000.4: log -p -3000 --histogram 1.73(1.62+0.09) 1.58(1.49+0.08) -8.7%
4000.5: log -p -3000 --patience 2.11(2.00+0.10) 1.94(1.80+0.11) -8.1%
Perhaps other platforms could also benefit. However it does NOT work
on big-endian systems!

Previously GIT_EDITOR was not listed in git(1) "Environment Variables" section,
which could be very confusing to users. Include it in "other" subsection along
with a link to git-var(1), since that is the page that fully describes all
places where editor can be set and also their preference order.
Also, git-var(1) did not say that hardcoded fallback 'vi' may have been changed
at build time. A user could be puzzled if 'nano' pops up even when none of the
mentioned environment vars or config.editor are set. Clarify this.
Ideally, the build system should be changed to reflect the chosen fallback
editor when creating the man pages. Not sure if that is even possible though.

In early days, all projects managed by git (except for git itself) had the
product of a fairly mature development history in their first commit, and
it was deemed unnecessary clutter to show additions of these thousands of
paths as a patch.
"git log" learned to show the patch for the initial commit without requiring
--root command line option at 0f03ca9 (config option log.showroot to show
the diff of root commits, 2006-11-23).

Sometimes one wants to see the different between two commits that are
a long distance apart in the graph display. This is difficult to do
with the "Diff this -> selected" and "Diff selected -> this" menu
items because the need to maintain the selection means that one can't
use the find facilities or the reference list window to navigate from
one to the other.
This provides an alternative using the mark. Having found one commit,
one marks it with the "Mark this commit" menu item, then navigates to
the other commit and uses the new "Diff this -> marked commit" and/or
"Diff marked commit -> this" menu items.
