Beak: is Not

What do people think of the following:

1) Remove LAST from the spec.  (Servers are of course free to continue
to support it as an extension.)

2) Add the following as an optional command:

           UIDL [msg]
               Arguments: a message-id (optionally)  If a message-id is
                   given, it may NOT refer to a message marked as
                   deleted.
               Restrictions: may only be given in the TRANSACTION state.
               Discussion:

                 If an argument was given and the POP3 server issues a
                 positive response with a line containing information
                 for that message.  This line is called a "unique ID
                 listing" for that message.

                 If no argument was given and the POP3 server issues a
                 positive response, then the response given is
                 multi-line.  After the initial +OK, for each message
                 in the maildrop, the POP3 server responds with a line
                 containing information for that message.  This line
                 is called a "unique ID listing" for that message.

                 In order to simplify parsing, all POP3 servers are
                 required to use a certain format for unique ID listings.
                 The first octets present must be the message-id of
                 the message.  Following the message-id is the 
		 identifier of the message. No information follows the
		 identifier in the unique ID listing.

		 The identifier of a message is an arbitrary 
		 server-determined string which uniquely
		 identifies a message and which persists across sessions.

                 Note that messages marked as deleted are not listed.

               Possible Responses:
                   +OK unique ID listing follows
                   -ERR no such message
               Examples:
                   C:    UIDL
                   S:    +OK
                   S:    1 whqtswO00WBw418f9t5JxYwZ
                   S:    2 QhdPYR:00WBw1Ph7x7
                   S:    .
                     ...
                   C:    UIDL 2
                   S:    +OK 2 QhdPYR:00WBw1Ph7x7
                     ...
                   C:    UIDL 3
                   S:    -ERR no such message, only 2 messages in
                         maildrop
