* From: Syd

* Revision 5.10 1992/12/07 04:31:38 syd
* Fix typo
* From: Syd
*
* Revision 5.9 1992/11/26 00:46:13 syd
* changes to first change screen back (Raw off) and then issue final
* error message.
* From: Syd
*
* Revision 5.8 1992/11/22 00:08:45 syd
* I was playing with the metamail stuff and Sun's Openwindows Mailtool
* and discovered that I was able to 'display' messages generated with
* Mailtool in elm using metamail. This marks the Sun Attachments as
* needing metamail.
* From: Lutz Brunke <brunke@dkrz-hamburg.dbp.de>
*
* Revision 5.7 1992/11/14 21:49:42 syd
* I think that the code in 'newmbox.c' which handles bad 'Content-length'
* entries is incomplete. The file-ptr for the mail file is
* backed up, but the file-ptr of the temp file WAS LEFT UNMODIFIED !
* From langesw.ssw.de!root Wed Nov 11 14:28:57 1992
