The reason I used the the %X/savename script was because I couldn't get
the quoting quite right to generate SAVENAME directly.  I since have, and
now use:

    SAVENAME="%\`echo %^C | sed -e 's/\\\\./\\\\//'\`"

As long as we are talking favorite rn hacks, I think it's a problem that
rn has per-user macro files, but only a global system initialization
file.  Well...I fixed that recently.  I moved the "rn" executable to
LIBDIR/rn, and instead place the following script in BINDIR:

    :
    INIT=$HOME/.rninit
    RN=/usenet/lib/news/rn/rn
    PROTO=/usenet/lib/news/rn/rninit-proto

    if [ ! -f $INIT ] ; then
	echo "$0: creating an '$INIT' startup initializations file" 1>&2
	cp $PROTO $INIT
    fi

    . $INIT
    exec $RN $@
    echo "$0: couldn't exec rn" 1>&2
    exit 1

This allows you to setup a "$HOME/.rninit" file with all your environment
initializations without polluting your environment outside of "rn".  For
example, my .rninit file says:

    AUTHORCOPY="$HOME/News/NewsCC"
    MAILRECORD="$HOME/News/MailCC"
    RNINIT="-v -S -hmessage-id -hreferences -hreply-to -hdate -hfollowup-to"
    KILLGLOBAL="%p/Killfiles/KILL"
    KILLLOCAL="%p/Killfiles/%c/KILL"
    SAVEDIR="%p/Savefiles"
    SAVENAME="%\`echo %C | sed -e 's/\\\\./\\\\//'\`"

    export AUTHORCOPY MAILRECORD RNINIT KILLGLOBAL KILLLOCAL SAVEDIR SAVENAME

The problem with this approach is that there are things run outside of "rn"
which need some of these initializations, e.g. Pnews needs "AUTHORCOPY".
I've cheated and kept those things in my login shell environment, but at
some point plan on hacking Pnews.SH and such to understand $HOME/.rninit.
