Because the official bazaar repository might be slow, we include an option for
pulling HEAD from an unofficial Git mirror:
brew install emacs --HEAD --use-git-head
There is inevitably some lag between checkins made to the official Emacs bazaar
repository and their appearance on the repo.or.cz mirror. See
http://repo.or.cz/w/emacs.git for the mirror's status. The Emacs devs do not
provide support for the git mirror, and they might reject bug reports filed
with git version information. Use it at your own risk.
