} MSG_SEPARATOR line to contain something other than simply a leading from_?

Mush accepts a number of formats for the From_ line.  The basic form is

	From address ctime-date

where the ctime-date is a 26-character date in ctime(3) format and the
address does NOT have any (My Name Here) or other comment fields.  Mush
intentionally does NOT recognize lines that do not match this format or
one of its dozen or so variations; if it did, this line:

>From the halls of Montezuma to the shores of Tripoli

(it did not originally have a leading ">", though some mailers may have
put one there) would incorrectly split this message into two parts.

That said, the most helpful thing I can probably do is to send you the
mbox.saver that I use.  It doesn't bother to strip the "Article N of ..."
or "Path:" lines, it just rewrites the arg list a little and then calls
the usual mbox.saver (the location of which probably varies from site to
site, look it up).  It sometimes runs into problems with RN's internal
buffer sizes for the argument list and so on, and it works better from
the "w"rite command than from the "s"ave command (with "s"ave you don't
really need to include the Subject: as I have at the end of this script).

#!/bin/sh
# mbox.saver -- sh script to save netnews articles via rn
# 
#	Arguments:
#	1 Full name of article (%A)
#	2 Public news spool directory (%P)
#	3 Directory of current newsgroup (%c)
#	4 Article number (%a)
#	5 Where in article to start (%B)
#	6 Newsgroup name (%C)
#	7 Save destination (%b)
#	8 Date and time (See below)
#	9 Name of poster (%t)
#	10 Subject (%s)
#
# This script is a "preprocessor" for the default mbox.saver (currently
#  residing in /usr/local/lib/rn).  It tacks a few extra words onto the
#  arguments it gets to make everything compatible with "mail -f", then
#  invokes the default saver.
#
# This script is intended to be used with the following rn environment:
#
# setenv MBOXSAVER '%p/mbox.saver %A %P %c %a %B %C \"%b\" \
#	\"rn %(%[posted]!=^\$?%[posted]:%(%[date]=^\(\w*\), \
#	\(\w*\)-\(\w*\)-\(\w*\) \([^ ]*\)?%1 %3 %(%2=..?%2: %2) %5 19%4))\n\" \
#	\"%f\n\" \"%s\"'
#
