I thought about the possibility of a warning too.  It seems like 
/[};]\s*$/ is the right pattern, but I have this feeling I'm forgetting 
some special case that will annoy users with correct grammars.  Actually, 
there could be trailing comments or cpp directives.

Alternatively, we could just formally deprecate it in NEWS now and then 
drop support as soon as it gets in the way of other languages.

I'll wait until we've settled this before pushing this fix to master.
