I gather you don't follow the AdaCore convention for comments.

It might be straightforward to modify your functions to deal with a
variable number of spaces after the comment chars. But that depends a
lot on what they do.

I guess that means checking if it is different than the default value.
Unless there is some 'custom-modified-p' function? (Help appropos
"custom.*modif" only returns custom-modified-face).

That might have been better in the first place, but it's not
backward-compatible now.

You can set comment-padding in ada-mode-hook (which is run after the
above code):

(add-hook 'ada-mode-hook
    (lambda () (setq comment-padding " ")))

or whatever you want it set to.

Is that sufficient?
