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)))))) -- Kevin Rodgers
