Actually, after looking a bit more we'd need more changes, the
`working-revision' is not passed to the `print-log' VC method, so a bit
more work would be needed for that :-(
But this does not affect my original proposal, which is still needed.

We show the terse log for directories already, but there's no way to
expand it (yet).  But even when using the terse log, there's still a
need to limit the log size.
