CC Mode: Fontify foo in "const auto foo :" correctly
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): While attempting to
find a declaration's identifier, recast the latest found id. as that
identifier when there is no other type identifier and the result of the most
recent c-forward-type call is 'maybe or 'found. In the latter case, remove
the id. from the found types list, too.
