The culprit is Jonathan's 3bf7886 (test-lib: Let tests specify commands
to be run at end of test, 2010-05-02). FreeBSD's /bin/sh doesn't
propagate $? over an eval:

  $ /bin/sh
  $ false; echo $?
  1
  $ false; eval 'echo $?'
  0
  $ eval 'false; echo $?' ;# but it still works inside, of course
  1

Looking at that patch, I don't see any reason that eval_ret needs to be
set inside the eval. If we have multiple test_when_finished calls, we
keep setting and propagating eval_ret, which doesn't make much sense to
me.  Why not just:

  test_run_ () {
    test_cleanup=
    eval >&3 2>&4 "$1"
    eval_ret=$?
    eval >&3 2>&4 "$test_cleanup"
    return 0
  }

  test_when_finished () {
    test_cleanup="$*; $test_cleanup"
  }

Am I missing something?
