By default we show porcelain, external commands and a couple others
that are also popular. If you are not happy with this list, you can
now customize it. See the big comment block for details.
PS. perhaps I should make aliases a group too, which makes it possible
to _not_ complete aliases by omitting this special group in
$GIT_COMPLETION_CMD_GROUPS
