bug#2421: 23.0.90; python-mode: Indent commands behavior

In GNU Emacs 23.0.90.1 (x86_64-pc-linux-gnu, GTK+ Version 2.12.11)
 of 2009-02-03 on blackbird, modified by Debian
 (emacs-snapshot package, version 1:20090202-1)

The indent commands `C-c <' and `C-c >' work only on active regions.
This is annoying, inconsistent with `C-x TAB' behavior, and not useful
(even if it worked as announced in its documentation, i.e. shifting the
current line, which it doesn't, a similar effect can be achieved more
easily by TAB presses).

So I suggest to change the behavior of these commands to always work on
the region, whether it is active or not, or to provide a configuration
option which can enable such a behavior.

Regards,
