To change only message.el is not enough. When I save a message to the
drafts folder and edit it then, then the text properties are not set
accordingly and I cannot -- for example -- add a long Cc without
auto-filling.

And: The read-only property of the mail-header-separator causes an
error.

This change
a. sets the 'field property to the header again (in
   `gnus-draft-edit-message')

b. sets inhibit-read-only to t for the erasion of the buffer. (in
   `gnus-draft-setup').

I tested it with GNU Emacs 21.0.106 and GNU Emacs 20.7 (both only on a
tty if that matters). I'm not familiar with XEmacs, so I could not set
it up appropriately to run Gnus. But I checked in the Lispref that the
functions/variables I added are known to XEmacs.
