Got it: the test I added contained an obvious syntax error made while 
saving, but since LilyPond did a good job it still managed to produce a 
PDF, and "systems.texi" appeared in the log.

Not sure wether there is a way to look for failed files more reliably. 
In the meantime, I found

cd input/regression
LC_ALL=C lilypond -d job-count=9 *.ly

to work well (LC_ALL=C needed because warnings are expected in English...)
