bug#6057: 23: py-indent-region broken

Thanks for filing this against gnu emacs. A couple of other things to note (if they're not apparent already):

1. python-mode now seems to be indenting automatically, without hitting tab -- You'll notice this whenever breaking a line in the middle by hitting return. This is a change from the previous behavior. (This one doesn't matter to me one way or the other... but I'm not sure the change was intentional.)

2. indentation is *extremely* slow -- I routinely have one-line nested python dictionaries (often many KB in length) that I'd like format, and I do this via keyboard macro that searches for the commas and inserts returns after them. Doing this in the latest version of aquamacs will max out my cpu for many minutes on end. The previous version could do this very quickly.

py-indent-region seems dysfunctional when we're at column 0.

Enter this:

if 1=1:
print 5
print 8
if 1=1:
   print 6
   print 6
   print 5

Then mark lines 2-5 (incl), which could be seen as a consistently indented block of code that was pasted there. C-c TAB should now shift it to the right, but it does nothing.

Contrast this with a situation where the block is already indented:

if 0=0:
   if 1=1:
   print 5
   print 8
   if 1=1:
       print 6
   print 6
   print 5

Select lines 3-6 (incl) and hit C-c TAB.  Works.

This is python.el from lisp/progmodes.

3. indent-region in python mode does nothing. (This happens in 2.0b5 too.) However, line-by-line indention (with tab) works.
