fix: don't include obsolete descendants with -s

The `-s/--source` option is for regular users (`-r` is there for power
users). If there are obsolete commits that are descendants of the
given revision(s), then they almost definitely should just be left
alone. That's what `hg rebase` does as well. So this patch makes it so
we skip obsolete commits (including those in the input set itself).
