$ lilypond source-file.ly |& tee /tmp/complete-errors | grep -v 'programming
error: must have stem dir for note head' | grep -v 'continuing, cross fingers'
Is this hackish enough? The unfiltered errors are available
for consultation in /tmp/complete-errors. I would need sed
rather than grep to filter out the second line only when
preceded by this particular first line.
