Repost: formalized the description and cleaned up stylistic errors

Description: 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".
