[PATCH] status: disable translation when --porcelain is used

[Matthieu Moy]

"git status --branch --porcelain" displays the status of the branch
(ahead, behind, gone), and used gettext to translate the string.

Use hardcoded strings when --porcelain is used, but keep the gettext
translation for "git status --short" which is essentially the same, but
meant to be read by a human.

Indeed, I'd call that a bug. Here's a fix.
