From 127df8c6cfd42ea666df9221d208b33b712d9994 Mon Sep 17 00:00:00 2001
From: Junio C Hamano <gitster@pobox.com>
Date: Tue, 12 Apr 2011 15:57:08 -0700
Subject: [PATCH] i18n: do not overuse C_LOCALE_OUTPUT (grep)

Instead of skipping the whole test, introduce test_i18ngrep wrapper that
pretends a successful result under GETTEXT_POISON build.
