Hey, sorry, I've been very busy in meatspace recently, and haven't
been on IRC as much as I would like.

The answer is in `makepkg:extract_hg()`: append `#branch=BRANCHNAME`,
`#revision=REVISION`, or `#tag=TAG` to the URL.

More generally, this is what you can specify for each VCS:

 - bzr
   * revision=
 - git
   * branch=
   * commit=
   * tag=
 - hg
   * branch=
   * revision=
   * tag=
 - svn
   * revision=

Happy hacking,
