[PATCH] Don't add 'p' delimiter when you shouldn't

[Phillip Susi <psusi@ubuntu.com>]

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.
