Well, I don't know about a dozen, but I did upgrade the commit message to
read as follows:
The reaction of kvm-recheck.sh is obscure at best, and easy to
miss completely. This commit therefore prints "BUG: Build failed"
in the summary at the end of a run. This commit also adds the
line of dashes in cases where performance info is not available,
and also avoids printing nonsense diagnostics in cases where
some of the normal test output is not available.
Does that help?
Thanx, Paul
