That is true. What we should probably do is to have some sort of
utility that can remove unwanted revisions from the database. I think
it should be up to the user to decide how and when this deletion
should be done. One option could be to keep all revisions newer than
the last version for instance. One of my motives for this is to enable
lxr to implement (or merge in) the features of both cvsweb and bonsai.
