This makes it easier, both for humans looking at the Travis CI web

A verbose commit message for such a change... but I don't know why we

Thanks for writing it up clearly.  TBH, I didn't even realize that
there were meaningful distinctions between the two cases after
seeing that sometimes our tests were failing and sometimes erroring
;-)

Should go on top of 'sg/travis-check-untracked' in 'next'.
