Re: Adding String to Beginning of Lines

[Christopher Dimech <dimech@gmx.com>]

I now have got 'rec-cont', which lets me pass a string.
How can I add a dafault  if I don't pass a regex in the
mini-buffer.

(defun rec-cont (beg end regex)
  (interactive "r\ns rec-cont regex: ")
  (replace-regexp "^" regex nil beg end))
  ;; (replace-regexp "^" ";; + " nil beg end))
