Please rest assured that the patch works, or at least works in all test
cases I could come up with.  It implements the behavior I described in
detail in my third message in this thread.

Put in another way, the patch makes ‘C-s y DEL x’ pretty much equivalent
to ‘C-s y☺\|x’, where DEL stands for `isearch-del-char' and ☺ stands for
an unmatchable regexp.
