If you know where to _find_ the ++version-lock directory then you
already know what `last-revision' would say.

The only time `commit' _has_ to look at the archive to find out the
latest revision is when the `--out-of-date-ok' option is given (I
mistakenly called that `--force' in my previous message on this
topic.)
