Seems to be caused by 149cc04782651e74764eb3188f6a6f178fe25f64, which is
unfortunate since that fixes (at least I *think* it fixes) some problems
when no default fore/background is defined (e.g. when emacs is run in
batch mode). It would be nice if this could be fixed without reverting
that commit completely.
