Hm, then I'm not sure whether it's worth for further similar
replacements.  A term "fallthru" is also very commonly used, and the
compiler knows it, too, so why bother to rewrite?

I don't mean to revert the already applied changes, but maybe better
to concentrate on fixing other real bugs (and/or real warnings).
