Maybe time-consuming, but in theory, everyone able to build lilypond
from git can write a little shell script that does the make clean
/ autogen.sh / make all / run the test combo and pass this script
to git bisect run. I didn't to this the other day, but next time I
will do.

I've already started work on an update of the ImageMagick package for
OpenBSD, and the regtest comparision already works here, too.
