The 'p' delimiter is supposed to be added when the base disk name ends
in a digit.  This decision was based on the name given on the command
line, not the canonical device name, so giving /dev/dm-0 instead of
/dev/mapper/foo triggered the digit test and added the 'p'.  Changed
test to use the canonical name rather than the given name.

    [kpartx] Don't add 'p' delimiter when you shouldn't
    
    The 'p' delimiter is supposed to be added when the base disk name
    ends in a digit.  This decision was based on the name given on the
    command line, not the canonical device name, so giving /dev/dm-0
    instead of /dev/mapper/foo triggered the digit test and added the
    'p'.  Changed test to use the canonical name rather than the given
    name.

Sorry, for some reason I was using
git://git.kernel.org/pub/scm/linux/storage/multipath/hare/multipath-tools.git,
and it's out of date.
