Previously, with -p, the specified directory and all of its parents would be 0777&~filemask (regardless of the -m flag). POSIX says parent directories must created as (0300|~filemask)&0777, and of course if -m is set, the specified directory should be created with those permissions. Additionally, POSIX says that for symbolic_mode strings, + and - should be interpretted relative to a default mode of 0777 (not 0). Without -p, previously the directory would be created first with 0777&~filemask (before a chmod), but POSIX says that the directory shall at no point in time have permissions less restrictive than the -m mode argument. Rather than dealing with mkdir removing the filemask bits by calling chmod afterward, just clear the umask and remove the bits manually.
