Subject: 29.0.50; Python indendation problem after comment

[Message part 1 (text/plain, inline)]

0. emacs -Q
1. C-x b test RET
2. Insert the following into buffer "test":

def test(n):
    if n < 0:
        return -1
    # test
    else:
        return 0

2. M-x python-mode RET (with buffer "test" current)
3. Put point on the line containing "else:" and type TAB
=> "else:" is dedented to column 0 and remains there on typing TAB
again (and again).

If the line containing "# test" is deleted and point put back on the
line containing "else:", then typing TAB indents "else:" to column 4
(where it was before being wrongly dedented) and remains there on typing
TAB again (as it should).

The same behavior happens with "elif" lines preceded by a comment line.

The attached patch prevents the wrong dedenting, but I'm not familiar
enough with the python.el code to be confident it's the correct fix.
