[PATCH v2] test suite: correct export var=val usage

[Jay Soffian <jaysoffian@gmail.com>]

Some shells do not like "export var=val", and the right way to write
these is to do an usual assignment and then export just variable names.

Also corrects a typo in the tests added by 94859732 and noticed by
Brandon Casey (gmane 110412):

    test_expect_success 'refusing to edit in refs/heads/' '
            (MSG=1 GIT_NOTES_REF=refs/heads/bogus &&
             export MSG= GIT_NOTES_REF=refs/heads/bogus &&
             test_must_fail git notes edit)
    '

    test_expect_success 'refusing to edit in refs/remotes/' '
            (MSG=1 GIT_NOTES_REF=refs/remotes/bogus &&
             export MSG= GIT_NOTES_REF=refs/heads/bogus &&
             test_must_fail git notes edit)
    '

    Notice the 'export' lines. Comparing it to Thomas's v2 5/5 patch, it
    looks like the first line which sets the variables is correct and
    the export line should just be 'export MSG GIT_NOTES_REF' in both
    tests.

This time with a better (I hope...) commit message to clarify
that we are fixing a typo and not introducing one.
