Yes, it fixes this, thanks.
The real problem I'm trying to track down is that the cursor is
sometimes put in the wrong position after a reverse-isearch. This was
what I came up with when trying to reproduce in a simple test case.
I'll run with the new patch and see if that helps my other problem
too (which can be a bit tricky to reproduce).
