The question is, do we regard this as an undocumented side-effect of
the implementation? Treating '-' and '0' as part of the width
specifier is conceptually simpler, and the elisp manual documents
these as such. If we treat '0' as a real flag, then maybe the
description in the elisp manual should be revised.
