Well, there is the problem that staff lines may be reconfigured in
thickness, but "apart from that (TM)", it would seem to me like counting
the half ledger line into the glyph height for the glyph intended to be
used on a staff line would not seem to cause problems, would it?  Or
would it shift material around that is designed to align to staff lines
and thus is not supposed to check for collisions with them for the sake
of placement?
