bug#22118: 23.2; Hitting ^W in a search selects the wrong word.

I don't know.  My patch tried to make the behavior in case of error
slightly more useful, but now I see nothing useful in it because
after a failure it makes no sense to type C-w C-w C-w ...

I don't recommend making code in isearch.el more complicated to handle
useless cases.  So I won't complain if you'll close this report.  :-)
