From d0835549442bd3288e1a33156f3d237a428292bc Mon Sep 17 00:00:00 2001 From: Jason Zaman Date: Thu, 28 May 2015 18:31:00 +0400 Subject: [PATCH] misc/install-xattr: ignore all whitespace in PORTAGE_XATTR_EXCLUDE if the PORTAGE_XATTR_EXCLUDE variable contains whitespace other than just ' ', the matching fails to exclude what comes after it. This replaces all whitespace instead of only just space.
