pmap man page is incomplete.

The man page for pmap (located at http://manpages.ubuntu.com/manpages/precise/en/man1/pmap.1.html) is incomplete in the following respect:

The "GENERAL OPTIONS" section notes that the -x option "Shows the extended format" and the -d option "shows the device format".

There is no documentation of what information the extended or device formats contain. The only hint given is in the STANDARDS section, which unhelpfully states "No standards apply, but pmap looks an awful lot like a SunOS command."

$ lsb_release -rd
Description: Ubuntu 10.04.3 LTS
Release: 10.04

This flaw in the documentation is current in the 12.04 documentation; the documentation hasn't been updated since 2002.
