Procmail weirdness

Discovered how to mark messages as read using procmail and maildir today. Turns out the trick involves renaming the mail after it's been delivered, thus:

MAILDIR=$HOME/Maildir :0 c $MAILDIR/ :0 ai * LASTFOLDER ?? ()\/[^/]+^^ | mv $LASTFOLDER $MAILDIR/cur/$MATCH:2,S

Way more complicated than using formail to add a "Status: RO" as used to be the way of things with mbox.
