I'm not sure about the '-r' option at all anymore.  I assume it was
created in order to make the old branch method (tag the base) work
well.  Then you could get the heads in the branch by doing:

hg heads -r branchtag

So, perhaps the -r option ought to be eliminated completely now.  I can
see how it might be useful when you're trying to figure out which
revision you want to 'hg strip' to remove a particular head but no
others.  But other than that I can't think why the '-r' option would be
useful anymore.

As it is, it's meaning is quite confusing, especially since all the
other arguments are revisions too.  It's hard to understand exactly
what's different about the revision specified by -r from all the others.

What it is is a base revision that any output must be a child of.

Have fun (if at all possible),
