I wonder whether using counts is the right solution: it doesn't
reflect typesetting (who ever uses !!!!! ?), nor musical meaning. It
seems like a quick hack. Can't we make up something neater for the
internal presentation?

The idea is that each Accidental grob prints only one #, natural or
b. Then accidental-placement figures out how to align them. This makes
it possible to use
natural #
in chords, and optionally place them like
natural #
(natural) b
natural #
