bug#17643: 24.3; Please remove comma bindings from french-prefix

It's usable now, but still annoying, since commas get underlined as
you type, which I find distracting.  But perhaps it's a simple matter
of habit -- I'm much more tolerant of apostrophes getting underlined.

Stefan, cedilla is not that common in French, so I think that keeping
it out of the way on "~" is the reasonable thing to do.  Additionally,
it's consistent with latin-prefix and latin-9-prefix.

            likes to claim he's the one who invented it)
