Gnus message mode used invisible text to hide headers while composing
a news/mail message.  But it was changed to use narrowing instead:

,----[ gnus/ChangeLog ]
| 2004-11-22  Romain Francoise  <address@hidden>
|       * message.el (message-header-format-alist): Add `From' in list
|       so that it can be sorted.
|       (message-fix-before-sending): Widen and sort headers before
|       sending.
|       (message-hide-headers): Use narrowing to hide headers by moving
|       them to the top of the buffer and narrowing to the region
|       underneath.

Bye, Reiner.
