Thanks, Juri.  That was not so obvious (for me).  The problem I noticed
appears also in builds (e.g. in October) that do not even have
`isearch--saved-overriding-local-map'.  Diffing the introduction of this
regression (in October) did not help me see what needed to be done.

I will close this bug.
