The stated objective does make sense, but ...

Any "cmd" that is run under test_might_fail that is *not* used for
its side effect is suspect---e.g. "we would try to remove this file
as the test may have created it, but it is OK if the file does not
exist and removal fails" is sort-of understandable, but I am having
a hard time imagining in what situation it makes sense for a test to
say "these two files may have the same contents but it is OK if that
is not the case".  There are a few others in this patch.

Another topic in flight tightens the allowed usage of test_must_fail
and test_might_fail helpers, and that is how I found this (because
the tip of 'seen' does not pass the test), but regardless of that
tightening, I am not sure what this "these two files may or may not
be equal" is trying to achieve.

Thanks.

I agree this is suspect, and I'm not sure what I intended there.  The
patch is unfortunately over two years old, so I don't recall exactly,
but it may have been flaky (in general) at the time I was changing the
test and I may have accidentally squashed that into the patch at the
time.

The test passes without it, so clearly the right thing is to remove the
test_might_fail, which I agree is bizarre.  Feel free to do that when
picking it up, and I'll fix that in in the reroll.
