Auto-subst of repository roots (was Re: svn diff branch woprking copy against mainline?)

A bunch of my gcc users are complianing that they are continually typing
the repository root to do certain diffs.
They are, of course right.
Usually, we just say "you can script with the shell", but as Richard
points out below, a substitution works everywhere, shell only works if
you are working in the same root everywhere.

Ignoring the question of what character would substitute repository
root, would anyone be opposed to having such a substitution.

For url vs url diffs, we'd look up the info from the current directory
(best we can do).

For url vs wc diff, one of the targets has to be in the wc, and we can
just get the repository root for that file (in case it is switched).
