Subject: [PATCH] git-sh-i18n.sh: add GIT_GETTEXT_POISON support
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Change git-sh-i18n.sh to support the GIT_GETTEXT_POISON environment
variable like gettext.c does, this ensures that tests that use
git-sh-i18n.sh will fail under GETTEXT_POISON=YesPlease if they rely
on Git's C locale messages without declaring that they do.
