This bit looks like it does a bit more magic than is immediately
obvious. Could you elaborate how this works?

Ok, so it looks like these are just declarations for things defined in 
common.opt - but why not move Wimplicit-fallthrough over to c.opt 
entirely, or alternatively keep everything in common.opt as it is now? I 
feel like I'm missing something.
