High-level review:

(a) Standardize '%r' and '%R' first.

As Adhemerval notes, this needs to go through POSIX or ISO C first
to standardize the '%r' and '%R' modifiers.

Working with the Austin Group is pretty easy actually, you need
to file a ticket with their system and discuss the change to the
standard:

Austin Group homepage:
http://www.opengroup.org/austin/

Austin Group bug tracker:
http://austingroupbugs.net/main_page.php

(b) Follow the contribution checklist.

After you have standardized the modifiers you go through the
contribution checklist here:

(c) Needs tests.

You need tests for all of the characters you are adding, and
the output they might generate.
