Force hg revert to delete instead of reverting

[Henri Wiechers]

I'm using mercurial 1.2.1 on Windows.

Sometimes I revert back to an revision (say x) to check some stuff and
then revert back to the tip.
I've noticed that when reverting back to tip that revert doesn't
delete files removed between x
and tip, instead it forgets them. Is there anyway to get revert to
delete them instead? I couldn't find a
switch for this.

Thanks,
Henri Wiechers
