IIUC the right way to do it is to use M-s w during the search to toggle
isearch-word, after which M-% should DTRT (just like M-% in regexp
isearch requests a query-replace-regexp).

Also, are you sure your patch works?  As far as I can tell, C-u
currently leaves isearch, and I don't see anything in your patch that
would change it.
