Would it be possible to tell LilyPond to assume a null dimension? After all
the mark is placed above the staff and sould not interfere with the note
spacing. Anyway I understand that these hacks should be avoided.

I will try it; by the way, where are these molecules inplemented? I 
would like
to give a look at the code. Maybe I can see a simple way to replace the
