Checking the exact contents of stderr typically fails when tests are run 
under -x. Perhaps

	test_i18ngrep ! "fatal: " actual.err &&"
	test_i18ngrep ! "error: " actual.err &&
	test_i18ngrep ! "warning: " actual.err

Which makes me wonder: Why would --show-description have to error out 
silently? This is not 'git config' after all.
