Comment #19 on issue 1320 by [email protected]: Enhancement: user-customizable barlines through a Scheme interface.
http://code.google.com/p/lilypond/issues/detail?id=1320
I also get many many regression test changes reported by `make check`.Most show no change in the images; probably moving the bar line to scheme changes the extents that `make check` uses for its comparison.
Several show real problems: 'bar-lines.ly', and anything with a repeat volta or \bar"".
