Mmh, I developed this patch originally under .48, and I had some severe
spacing problems which I tried to minimize.  With the new code for grace
notes in spacing-spanner that you put into .49, these errors disappeared;
so, maybe distance can now always be set to max_note_space, but in .48,
the breaking algorithm obviously assumed tighter spacing than the grobs
(especially rests and clef changes) were finally typeset, resulting in
score lines getting too long.

Sounds reasonable.  I will be travelling for the next two or three days,
but after that I'll be back and have a look at it.

Thanks for putting in the patch!
