Albeit no. I'm using `cycle-spacing' with the following binding:
(define-key esc-map " "
(lambda (n) (interactive "*p")
(cycle-spacing (- n) t)))
and I sometimes end up with a situation like this one:
const unsigned long long foo =-!-
calculate_stuff() * calculate_other_stuff();
(-!- denoting point) in which case I don't know if I want 1 space or
whatever there is now. What I end up doing is hit M-SPC to end up with:
const unsigned long long foo = calculate_stuff() * calculate_other_stuff();
and if it fits in my window (which is 80-character wide) I go on with my
life, if it does not, I press M-SPC two more times.
(And before you ask, yes, I am aware of M-^ and C-_ but see below.)

Sure, but:
* It is *much* easier to press the same key sequence three times in
a row than to use different key sequences. Compare:
- hold ALT down
- press SPACE
- press SPACE
- press SPACE
- release ALT
with:
- hold ALT down
- press SPACE
- press \ (which in many keyboard layouts is on far right which
forces you to extend your pinky)
- release ALT
- hold SHIFT and CTRL down
- press _
- release SHIFT and CTRL
* I find it easier to remember one key sequence that does magic stuff
then to remember bindings for everything. I never use M-\ and don't
have to remember it's there because M-SPC almost always does what
I want it to do if I press it enough times.
Similarly, I have no idea what is the key binding is for going back to
indention or to the beginning of buffer since my C-a does all that for
me.
BTW. M-\ does not work on new line characters whereas `cycle-spacing'
can.

Hope the above helps.
