Marc Ries refers to two interesting problems in the utility shell
scripts supplied with the Elm system:

1. 'messages' doesn't like when you're not on a machine that has
   $MAIL defined.  I never thougth of that (!) and shall change it
   as suggested.  Thanks!

2. the reason that 'trim-headers' isn't doing much for you is 
   because you're handing it something that isn't a valid mail 
   message, so it, correctly, isn't touching it.  Let's look at
   the example message:

   The problem, of course, is that it isn't an RFC-822 conformant
   message text, so the program cannot actually distinguish between
   the message 'header' (aka the "envelope") and the message 'body'!

   If you were to add a line "From gallagher Thu Sep  3 00:26:56 PDT 1987"
   at the beginning you'd find it chopped down quite a bit.  Alternatively,
   you *could* modify the trim-headers script to know that "Path:" is also
   an 'enter-message-header-state' prefix (just hope that it doesn't occur
   in the *body* of any of the messages you have saved...)
