Close examination of the output reveals that the open end of the hairpin 
extends slightly beyond the stem. I wonder what kind of threshold should be 
used to decide on a new length. One might be: if the end of the hairpin is 
within x horizontal distance from the stem, shorten it until it is not. Maybe?

I'm considering taking this on as my first contribution, and i'm trying to work 
my way through lilypond's typesetting process until i understand enough to 
figure out how to make a change like this. Developers, am i thinking in the 
right direction?

In cross-staff situations, it may happen that the open end of a hairpin is 
completely shut by a stem. The end of the hairpin should be slightly shortened 
in such situations.
