xdiff performs "classification" of records (xdl_classify_record()),
replacing hashes (xrecord_t.ha) with a unique identifier of the
record/line and building a hash table (xrecord_t.rhash) of records. This
is then used to "cleanup" records (xdl_cleanup_records()).
We don't need any of that in histogram diff, so we omit calls to these
functions. We also skip allocating memory to the hash table, rhash, as
it is no longer used.
This gives us a small boost in performance.

Port JGit's HistogramDiff algorithm over to C. Rough numbers (TODO) show
that it is faster than its --patience cousin, as well as the default
Meyers algorithm.
The implementation has been reworked to use structs and pointers,
instead of bitmasks, thus doing away with JGit's 2^28 line limit.
We also use xdiff's default hash table implementation (xdl_hash_bits()
with XDL_HASHLONG()) for convenience.

This in preparation for the histogram diff algorithm, which would also
re-use these test cases.

Michael J Gruber noticed that under /bin/dash this test failed
(as is expected -- \n in the string can be interpreted by the
command), while it passed with bash. We probably could work it
around by using backquote in front of it, but it is safer and
more readable to avoid "echo" altogether in a case like this.

When we run tests under valgrind, we symlink anything
executable that starts with git-* or test-* into a special
valgrind bin directory, and then make that our
GIT_EXEC_PATH.
However, shell libraries like git-sh-setup do not have the
executable bit marked, and did not get symlinked. This
means that any test looking for shell libraries in our
exec-path would fail to find them, even though that is a
fine thing to do when testing against a regular git build
(or in a git install, for that matter).
t2300 demonstrated this problem. The fix is to symlink these
shell libraries directly into the valgrind directory.

The valgrind target just reinvokes make with GIT_TEST_OPTS
set to "--valgrind". However, it does this using an
environment variable, which means GIT_TEST_OPTS in your
config.mak would override it, and "make valgrind" would
simply run the test suite without valgrind on.
Instead, we should pass GIT_TEST_OPTS on the command-line,
overriding what's in config.mak, and take care to append to
whatever the user has there already.

v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are
handled, 2011-04-29) tried to make gitweb's tag cloud feature more
intuitive for webmasters by checking whether the ctags/<label> under
a project's .git dir contains a number (representing the strength of
association to <label>) before treating it as one.
With that change, after putting '$feature{'ctags'}{'default'} = [1];'
in your $GITWEB_CONFIG, you could do
echo Linux >.git/ctags/linux
and gitweb would treat that as a request to tag the current repository
with the Linux tag, instead of the previous behavior of writing an
error page embedded in the projects list that triggers error messages
from Chromium and Firefox about malformed XML.
Unfortunately the pattern (\d+) used to match numbers is too loose,
and the "XML declaration allowed only at the start of the document"
error can still be experienced if you write "Linux-2.6" in place of
"Linux" in the example above. Fix it by tightening the pattern to
^\d+$.
