bug#72311: [PATCH] Treat period as a symbol constituent in cc-mode

You are right, kind of forgot about that.  I think in that case a simple
syntax table modification like my patch provides won't do the trick.

My motivation for this patch was to able to use C-M-f (forward-sexp) to
skip over decimal numbers.  What are your thoughts on defining a
forward-sexp-function that will use a alternate syntax table in certain
contexts? maybe a bit too hacky?
