From 46ec9e3548b5b567c7eb18c360f54a77b6313b12 Mon Sep 17 00:00:00 2001
From: Nathan Jones <nathanj@insightbb.com>

Subject: Make it easier to ignore multiple packages.

This makes --ignore and --ignoregroup able to accept multiple
packages/groups by separating each with a comma.

For instance: pacman -Su --ignore kernel26,udev,glibc

This was requested in the comments of FS#8054.
