It is not wrong per-se, but >redirection without a number redirects
fd#1, so "1>actual" is an unusual way to spell ">actual".

test_must_fail mustn't be used like that for two reasons

 - It is to be used for "git" stuff, because it knows failing with
   segfault and other failure modes are _wrong_ and should not be
   happy even if the command "fail"ed.  We however do not expect
   commands that are not git (e.g. test_i18ngrep) to require special
   casing of the failure modes.

 - test_i18ngrep pretends to always "have found match" when running
   under GETTEXT_POISON build, so it will pretend that usage exists
   in actual.error.  test_must_fail will then say "oops, the string
   'usage' shouldn't appear in the output but it did", which is not
   what you want.

Perhaps

	test_i18ngrep ! "usage" actual.err

is what you want to say here instead.

In any case, the tests got a lot cleaner compared to the previous
round, and I feel that this patch is "getting there" ;-)

Thanks for working on it.
