Subject: [PATCH] Commit fb71f0d introduced to possibility to add options
 behind permissions in fstab. Unfortunately it breaks scenarios where no
 options are provided as the current regex expects the comma with the options
 always to be present.

This patch fixes the regex to handle the options as group.
