This happens when there's a conflict on a path, and then one of the next
revisions to merge need to apply a change to that (now conflicted) path.

Yes, I know. I've often wished it would remember the revision range that
was entered.

But: in most situations, the merge failed because either the revision
range or the merge url was wrong in the first place. That's why I never
implemented a 'remember' feature.

If a merge fails for me, I usually revert the whole working copy before
trying the merge again.

not quite as easy as it may seem. There's no guarantee that when the
merge dialog is opened again that it's opened on the same path or for
the same merge.
