But the next line _is_ a comment so the warning is inappropriate here.

If this were a very unlikely situation, fair enough.  But people do
comment out multi-line macros from time to time using `//', and those
will trigger the warning.

It can't be too hard to skip whitespace and then check for `//' on the
next line I'm sure.
