From 785063e02bb249ef3a39db88575fe626b310d4a7 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 8 Aug 2012 12:08:17 -0700 Subject: [PATCH] sh-setup: protect from exported IFS Many scripted Porcelains rely on being able to split words at the default $IFS characters, i.e. SP, HT and LF. If the user exports a non-default IFS to the environment, what they read from plumbing commands such as ls-files that use HT to delimit fields may not be split in the way we expect. Protect outselves by resetting it, just like we do so against CDPATH exported to the environment. Noticed by Andrew Dranse .
