By the way, didn't we have a remote-svn prototype?  I'm happy to merge
any old hacky thing for staging in contrib/svn-fe, as long as it is
not documented in a misleading way.

(More generally, if anyone wants to resend useful svn-fe patches, that
will help a lot.)

corresponds to each commit, and marks or lightweight tags going the
other way?

Sure would be neat. ;-)  Another nice piece to build would be branch
tracking / follow_parent heuristics.
