Thanks; applied.

Right. Could you fix that? :-)

Right... but it feels kinda hackish to add the check for just
`byte-compile-warnings' there, since we don't have access to the
category at that point, so I altered the call site instead. But perhaps
`macroexp-warn-and-return` should just be extended with a category
parameter and then the check moved into the function instead... I dunno...
