[PATCH v4 0/5] TAP support for Git

This is v4 of the TAP series for Git. This version fixes the failure Junio had with it (see <7v6319duky.fsf@alter.siamese.dyndns.org>).

It does this by reverting the removal of the test_external_* functions. Now they're made TAP aware instead with a global `test_external_has_tap' that can be set by tests who wish to output their own TAP.

Thus t9700-perl-git.sh will again fail if it has any output on stderr, but since it sets `test_external_has_tap=1' we'll let it finalize its own TAP plan.

Not removing the test_external_* makes the impact of this series smaller, and preserves compatibility with other topics in-flight, such as the Gettext series.

This is the diff --stat from v3:

 t/test-lib.sh       |   97 ++++++++++++++++++++++++++++++++++++++++++++++++--

Most of the additions are the restorations of the test_external_* functions, in slightly altered form.

Ævar Arnfjörð Bjarmason (5):
  test-lib: Adjust output to be valid TAP format
  test-lib: Make the test_external_* functions TAP-aware
  test-lib: output a newline before "ok" under a TAP harness
  tests: Skip tests in a way that makes sense under TAP
  tests: Say "pass" rather than "ok" on empty lines for TAP
