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

| 
| 	* 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.
