That's all exactly right.  Thanks!

Fred used to keep good track of this, so I doubt there's a big backlog.  I
expect the best candidates are those (like the re tests) recently converted
to unittest.  Getting rid of expected-output files should be part of such a
conversion (or of a conversion to doctest).  OTOH, the expected-output kind
of test remains fine by me!  It used to be very painful to see what went
wrong when things failed, but quite some time ago that mechanism was
reworked to save all the output and display a diff instead.
