I'll not likely be able to do work on this before tomorrow afternoon,
but I'm not forgetting it.  If anybody else wants to have a go for it:
basically all this commit does is remove the code that refuses to
typeset zero-length music, and then fix everything that segfaults
because of being unable to deal with empty stuff.  Obviously not
everything...

You need to compile without optimization and need to get around with the
debugger.  I don't have more of a clue than that, either.
