Could anyone explain to me what the subst-char-in-region in
gnus-get-newsgroup-headers in gnus-sum.el is there for? It replaces tabs with
spaces in the nntp-server-buffer, which of course breaks the overview headers
badly. Is this only supposed to be run for non-overview headers? I don't get
it.

(defun gnus-get-newsgroup-headers (&optional dependencies force-new)
  (let ((cur nntp-server-buffer)
	(dependencies
	 (or dependencies
	     (save-excursion (set-buffer gnus-summary-buffer)
			     gnus-newsgroup-dependencies)))
	headers id id-dep ref-dep end ref)
    (save-excursion
      (set-buffer nntp-server-buffer)
      ;; Translate all TAB characters into SPACE characters.
      (subst-char-in-region (point-min) (point-max) ?\t ?  t)
