Pavel Roskin 41184273d1 [PATCH] Trapping exit in tests, using return for errors: further fixes.
"return" from a test would leave the exit trap set, which could cause a
spurious error message if it's the last test in the script or
--immediate is used.

The easiest solution would be to have a global trap that is set when
test-lib.sh is sourced and unset either by test_done(), error() or by
test_failure_() with --immediate.
