Yes, i think that is enabled and working (indenting a comment block).
That is not working always correctly is indenting code after a block of
comment if this comment is commented with M-;. May be it's only because
M-; comment with only one # with no space in front.
Sure it can be corrected, i never ask myself about that as i use C-c #
in python.
