I'm starting to think of some kind of an overlay over Mercurial/git/... which would keep a couple "disabled" repository meta-directories, let's say:

.hg1/
.hg2/
.hg3/

etc., and then on hg commit FILENAME would find the particular .hgN that is linked to FILENAME, and would then temporarily:

mv .hgN .hg
hg commit FILENAME
mv .hg .hgN

The main disadvantage is that it would require me to spend some time writing the tool. Or does anybody know of some ready-made one like this? If you do, please post as a full-featured answer (not a comment), I'm more than willing to accept it.
