dmraid was changed at one point to insert a 'p' between
the base device name and the partition number. For
some time debian and ubuntu reversed this change. This
patch modifies the behavior to add the 'p' iff the last
character of the base name is a digit. This makes
dmraid comply with the behavior used by kpartx and
"by linux since the dawn of time".
