Without directly answering that question, I have found that using the
List-Id header is much nicer.  And, it can be used to automatically
filter a lot of lists with one rule, rather than having separate rules
for each list.  Here's an example to illustrate:

# automagically handle nice standards conforming mailing lists.
# taken from http://spacepants.org/conf/dot.procmailrc,
# where it was attributed to Jeff Waugh
:0
* ^List-Id: +\/.*
{
    LISTID=$MATCH

    :0
    * LISTID ?? ^.*[<]\/[^@>\.]*
    lists/$MATCH/

    # the ^ * seems ineffective at removing spaces, best to be sure
    # the initial pattern does this (e.g.: ^List-Id: +\/.*)
    :0
    * LISTID ?? ^ *\/[^@\.]*
    lists/$MATCH/
}

# try to match List-Post headers
:0
* ^List-Post: *[<]mailto:\/.*
{
    LISTPOST=$MATCH

    :0
    * LISTPOST ?? ^ *\/[^@]*
    lists/$MATCH/
}

This handles most of my lists.  Only a few that I want filtered into
mailboxes that don't match the name used in the List-Id or that don't
use a List-{Id,Post} header need explicit rules.
