Great!  I've wanted this for a while, but when I took a look at the code
I could see it was gonna be a lot of work to handle hashed repositories
(OTOH, I don't think I knew about "darcs show" at the time).

That would probably be ESR.

To clarify: it requires darcs 2.0.0 or higher -- but it still supports
repositories in darcs-1 (old-fashioned-inventory) format?

I looked at (info "(emacs)Registering") but I don't really understand
what this means.  Is registering something for RCS/CVS that Darcs users
don't need to know about, other than "don't use it"?
