elm mishandles large uuencoded messages

[Dave McQuate]

  I've had problems with "elm" corrupting its mailbox when a number of
large uuencoded messages are received.  (Say ten 40kbyte messages)
When the problem occurs, if I try to read previously received text messages,
I see what seems to be portions of the uuencoded messages instead.  If I'm
on my toes I can work around it by making a copy of /usr/mail/davem, exiting
elm, then restoring /usr/mail/davem from the saved copy.

  Also, sometimes when I try to save these uuencoded messages before I've
read them--I.E. I save from the index page--the saved file has zero length.

  Any hints?
  Thanks.
