We had --heads for refs/heads and --tags for refs/tags, but no easy
way to specify refs/remotes, which is going to be more common now that
it's the default layout for clone.
Also add remotes to --all and update documentation.

Another patch in my "features I wasted time looking for" series.
I figure that patches are more useful than feature requests, and
that seems to be proven by the fact my patches are getting applied.
This is my first serious foray into git's C code. I simply copied
append_head_ref to get append_remote_ref, since the goal was similar.
If there are additional checks that would need to be done in there,
feel free to fix it, or tell me what I should look for.
As a side note, there's no documentation for the --topics option for
show-branch. If I figure out what it does, I'll write it, but I'd bet
someone else already knows and would love to help a neophite git coder
figure it out. ;-)
