From 69ae92bda13dfbf0b7d169c57b9f2715af2a9d67 Mon Sep 17 00:00:00 2001
From: Junio C Hamano <gitster@pobox.com>
Date: Wed, 13 Oct 2010 11:36:36 -0700
Subject: [PATCH] shell portability: no "export VAR=VAL"
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

It is more portable to say "VAR=VAL && export VAR" instead.

Noticed by Ævar.
