That's what we seem to be doing in the tests so far, i.e. test_must_fail
is reserved for git commands only.

test_must_fail relies on conventions for return value that cannot
necessarily be relied on from outside utilities.

Right, someone should send a patch for these:

    ack 'test_must_fail (?!git)' *sh

:)

You joke, but thanks to your prodding, I discovered these broken
tests that should definitely all be fixed:

   $ perl -ne 'm/test_must_fail +[^ ]+=/ && print' *sh

        test_must_fail PAGER= git reflog show delta &&
        test_must_fail PAGER= git reflog show epsilon &&
        test_must_fail PAGER= git reflog show epsilon
        test_must_fail PAGER= git reflog show zeta &&
        test_must_fail PAGER= git reflog show eta &&
        test_must_fail PAGER= git reflog show eta
        test_must_fail PAGER= git reflog show beta
        test_must_fail MSG="yet another note" git notes add -c deadbeef &&

one-shot variable assignment does not work with test_must_fail.

See e2007832552ccea9befed9003580c494f09e666e for an explanation.
