    Quote mount point when resizing jfs (#782681)
    
    Attempting to grow an already mounted jfs where the mount point
    contained spaces failed like this:
    
        Grow /dev/sdb2 from 1.00 GiB to 1.50 GiB
        + calibrate /dev/sdb2
        + grow partition from 1.00 GiB to 1.50 GiB
        + grow file system to fill the partition
          + mount -v -t jfs -o remount,resize /dev/sdb2 /tmp/File System Label
            Usage:
            mount [-lhV]
            mount -a [options]
            mount [options] [--source[ <source> | [--target] <directory>
            mount [options] <source> <directory>
            mount <operation> <mountpoint> [<target>]
            ...
    
    Apply the rule to always enclose mount points within double quotes
    within command lines.
