That is much better yes. I allready did something like that:
  (goto-char (point-min))
  (re-search-forward "^=" nil nil)
  (forward-line 2)
  (delete-region (point-min) (point))
  (re-search-forward "^=" nil nil)
  (beginning-of-line)
  (delete-region (point) (point-max))

Because the buffer has to be deleted from the beginning, I do not need
to save the point. But otherwise it should be done offcourse.

Thanks for the info.
