Perhaps you're not setting it correctly in .emacs. Try, in a .pro buffer,
C-h v comment-add. It should say something like:
comment-add is a variable defined in `newcomment.el'.
Its value is 1
Local in buffer foo.pro; global value is 0

This is the correct behavior, since any comment starting at the
beginning of the line is not moved when indenting. If you always want
it to indent no matter where point is, perhaps inset " ;{{{" instead.
By the way, for "folding", the next version of IDLWAVE will support
HideShow, which lets you collapse blocks (routine definitions or
otherwise) with a few keystrokes. Very useful, and no comment
trickery required. A hidden function, for instance, look like:
function my_func,arg1,arg2...
but contains the full collapsed text. Sometimes I find it useful to
collapse (C-c @ C-M-h) everything, and then show a few functions at a
time. You can also hide any control block.

In that case just stick it in the global map.
(define-key global-map
[f6]
'(lambda () (interactive)
(insert (concat " " comment-start "{{{"))
(indent-according-to-mode)))
