Summary: python-mode loops on if/else

Initial Comment:
(migrating from python project)

Original submission:

Here's how to reproduce.  Create a .py file in XEmacs 
 containing this text: 
  
 x = (if 1: 2 
  ____else: 3) 
  
 (except that the ____ really means four spaces). 
  
 Now position your cursor somewhere inside those 4 
 spaces, and hit TAB. XEmacs freezes until you hit 
^G.

The code gets into an infloop in py-outdent-p.  The 
loop looks
odd to me:

  (while (or (looking-at py-blank-or-comment-re)
                (bobp))
     (backward-to-indentation 1))

If you were at (bobp), why would you want to try to 
move back
a line?
