a regexec_buf() helper that takes a <ptr,len> pair with REG_STARTEND
extension.

* The procedure to build Git on Mac OS X for Travis CI hardcoded the
internal directory structure we assumed HomeBrew uses, which was a
mechanism to avoid digging too deep into irrelevant side branches.
This however did not work well over the "smart-http" transport due
to a design bug, which has been fixed.

complete "git cmd ^mas<HT>" to complete the negative end of

the same when the username is explicitly set to an empty string.

* The "submodule.<name>.path" stored in .gitmodules is never copied
to .git/config and such a key in .git/config has no meaning, but
the documentation described it and submodule.<name>.url next to

* "git send-email" attempts to pick up valid e-mails from the

output separately to the log file.
