See also the thread "be able to replace during isearch" at the beginning of
July 2007. The idea is to replace particular search hits on demand, during
isearch. This is quite different from a query-replace approach, where you
are asked about each hit. You just hit a key if you want to replace the
current hit. A different key would let you redefine the replacement string.
