Thanks.
Is it possible to do a search and replace automatically as a "hook" to
comment-region????
The file will have this problem as "\n# \n".
I just have to replace that with "\n#\n".
I believe this is called a regular expression??
Can they be run every time we do a comment-region?
You can always try (this is completely untested):
(defadvice comment-region (after unpad-blank-line-comments)
"If blank lines are commented, delete `comment-padding' on those lines."
(if (and (null (ad-get-arg 2)) ; (null ARG), (null current-prefix-arg)
comment-empty-lines)
;; We are commenting, not uncommenting.
(let ((empty-comment-regexp (format "^[ \t]*\\(%s\\)\\(%s\\)$"
comment-start
comment-padding)))
(save-restriction
(narrow-to-region (ad-get-arg 0) (ad-get-arg 1)) ; (... BEG END)
(goto-char (point-min))
(while (re-search-forward empty-comment-regexp nil t)
(replace-match "" nil nil nil 2))))))
