I recently changed the copyright headers in XML files in one of my

However, this doesn't play well with my formatting fixup function:
(defun ide-fix ()
  "Remove trailing spaces and fix indentation"
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (replace-regexp "[ \t]+$" "")
    (goto-char (point-min))
    (replace-string "\t" " ")
    (indent-region (point-min) (point-max))))


After running "ide-fix", the indentation of the first line is kept, but
all of the other lines are moved to the left margin:

Is it possible to make nxml preserve the original indentation in these
comments?

(Or should I just bite the bullet and go back to the old copyright
headers?)

Thanks!
