I've been having a problem generating multimeasure rests within
leadsheets, and until recently I made no serious attempt to figure
out what was going on. What I finally noticed is that lilypond
doesn't generate multimeasure rests when I use the chordnames context.
If I comment out the chordnames part of the score, lilypond correctly
generates multimeasure rests.
I haven't seen anything in the archives addressing this issue, so
I wonder if I've been missing something obvious. I am currently
using version 2.11.27 under windows, although I noticed this problem
with version 2.10.x as well. I've attached a copy of one of the
leadsheet files that exhibits this behaviour..
