Whoops, this should have an extra "-", of course (I got this wrong in
the cover letter, too). I.e.:

  test_expect_success 'whatever' - <<\EOT
     ...
  EOT

It would be nice to drop it, but then:

  test_expect_success PREREQ 'whatever' <<\EOT

becomes ambiguous (and I don't think there is a portable and reliable
way to decide that our input is coming from a here-doc versus the
original stdin).
