Actually, removing the most recent N revisions is much easier than
"svn obliterate", because earlier revisions cannot possibly have
dependencies on later ones. A correct but inefficient approach would
be simply to delete those rowse from the `revisions' table; nicer
would be to remove the corresponding stuff from `nodes' and `strings'.

Of course, working copies would be invalid, but detectably so -- at
least until new revisions using the same numbers are committed.
