Funny \/ handling?

Using the following procmail script fragment:

    LOGFILE="${HOME}/PROCMAIL.LOG"
    VERBOSE="on"
    LOGABSTRACT="all"
    #
    :0 wh
    SENDER=| formail -rzx To:
    #
    :0 wfh
    * ? test "${SENDER}" != "foo(_at_)bar"
    | formail -I "X-Delivered-Sender: ${SENDER}"
    #
    :0 wfhE
    | formail -A "X-Diagnostic: No machine generated return address"
    #
    :0
    * ^from \/[-0-9a-z(_dot_)_+=?]+(_at_)[-0-9a-z(_dot_)_+=]+
    { ENV_FROM="${MATCH}" }
    #
    :0
    /dev/null

with the following email, (the envelope from record was intentionally
omitted):

    Received: (qmail 20654 invoked by uid 501); 29 Oct 2002 00:09:38 -0000
    Message-ID:

    To: someone(_at_)somedomain(_dot_)com
    Subject: asdf
    Date: 29 Oct 2002 00:09:38 -0000

    asdf

gives a PROCMAIL.LOG, "procmail fragment < email" was used):
