Jeff King 60687de5ba t: fix moderate &&-chain breakage
These are tests which are missing a link in their &&-chain,
but in a way that probably does not effect the outcome of
the test. Most of these are of the form:

  some_cmd >actual
  test_cmp expect actual

The main point of the test is to verify the output, and a
failure in some_cmd would probably be noticed by bogus
output. But it is good for the tests to also confirm that
"some_cmd" does not die unexpectedly after producing its
output.
