Maybe I should have said "...not to try this myself..." to make it
clearer: The approach you outlined sounds not only reasonable but the
perfect solution to this and other problems. But it's over my head and
time limit (and it's not my itch either). It touches the inner core
(index format and handling) and needs to be done diligently, too much
for a quick patch on the side of my $DAYJOB. (Though, thinking about it:
some colleagues use a similar hg feature to revision stamp their LaTeX
preprints, and working Id could help win them over.)
