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


From: David Reitter
Subject: bug#6057: 23: py-indent-region broken
Date: Tue, 27 Apr 2010 21:50:52 -0400

X-Debbugs-Cc: Warren Harris <address@hidden>

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
else:
    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
else:
    print 6
    print 5

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

This is python.el from lisp/progmodes.
