Re: Unconventional score and unwanted stray staff lines

[David Bellows]

Hey Mark,

This music is generated algorithmically and there are a lot of options
for the user to choose from, so one never knows what's going to
happen. I need for Lilypond to do its usual thing and look perfect
without any additional user interaction.

For example, I left out of these examples the scheme code that
automatically adds ottava markings based on the instrument and so on.
