do_update() assumes you're comparing the same path in two different
revisions. do_switch() assumes you're comparing two different paths.

The diff and merge command might be comparing anything; the paths
could be identical, or totally unrelated. So they call do_switch(),
since that's always guaranteed to work.

Rather than create a whole new do_diff(), maybe we can add a new flag
to do_switch() that indicates whether we want the vsn-rsc-url data
sent back to us.
