Those samples break if the mount point directory name contains spaces, tabs, or whatever other characters I don't know about that also get represented by escape sequences. I'm not actually using it with /etc/fstab, but with /proc/mounts which uses the same convention. I can control /etc/fstab and avoid the problem, but I cannot control how some auto-mounted foreign filesystem might be named. I have a script that needs to be robust in the face of such names.
