All of my C++ work on LilyPond (the elimination of translate_axis, for example) 
is going towards improving cases like this.  That said, this case is 
particularly thorny.  To fix it, you could add an invisible text spanner above 
the beam with the gs, for example.

I'd send this sort of question to -user, as people have all sorts of hacks for 
this kinda thing.
