Right, but I was thinking of a simpler scenario. User only ever works
on trunk, does not even do branching. They want to do undo a commit.
There is no mergeinfo at all. They ought to be able to do this and it
sounds like with the current code they can't. So this needs to be
fixed and "special-cased" regardless. Now, I also think that doing
this fix also provides a reasonable solution to the problem in
general, but we'll have to see what Dan and others have to say.
