I checked in your suggestion as

	* progmodes/python.el (python-shift-left, python-shift-right):
	When the mark is not active shift the current line.  (Bug#2381)
	Suggested by Guillaume Salagnac <guillaume.salagnac <at> gmail.com>

Thanks for the report, martin.

In Python mode (the one provided by lisp/progmodes/python.el) there  
are two functions that look very handy for indenting/reindenting  
code : python-shift-left and python-shift-right.

According to their documentation string, they can work either on the  
current active region, or on the current line if the region is not  
active. However, this latter feature does not seem to work properly.

Steps to reproduce error: open emacs, type M-x python-mode, type some  
code, and try "C-c <" or "C-c >" with no active region.

A simple fix seems to be achieved by replacing this "(point) (point)"  
default value, which is obviously empty, by  "(line-beginning- 
position) (line-end-position)" in both functions.

Cheers,
-Guillaume
