Ah, now I see.  This was not a regression from Darrick's patch, but
rather a pre-existing failure.  One that I hadn't noticed because I
don't have libmagic-dev installed on my new development laptop.  :-)

I've checked in a fix into my repository.

Subject: [PATCH] tests: fix expected output for f_detect_junk

The expect files for f_detect_junk had gotten out of sync with the
code base, and since this test is optional (it depends on libmagic
being installed), we hadn't noticed.
