I missed this bit in the patch you pointed out:

+       test "z$(grep ^X-Mailer: out | wc -l)" = "z$expected"

which depends on "wc -l" not to add any extra whitespace around its
count.  We know that some implementations do, and we should be using

	test $(grep xxx | wc -l) -eq $expected

or something, or test_line_count.

Thanks for noticing.
