Regarding the new parameter parsing for the IMAP server:

At the moment, FETCH args are parsed with ParseNestedList, which means that
any items inside [] are appended as an additional list.

For example, this command:
    0003 FETCH 1 BODY.PEEK[HEADER.FIELDS (References X-Ref)] UID
    ['BODY.PEEK', ['HEADER.FIELDS', ['References', 'X-Ref']], UID]

There are really two items that have been requested - BODY.PEEK and UID, but
the args list has three, because the BODY.PEEK information has been split
into a separate item.

It seems to me that it would make more sense for the result to be:
    [['BODY.PEEK', ['HEADER.FIELDS', ['References', 'X-Ref']]], UID]
Or something like that, which keeps the body.peek information together.
(Note that BODY and BODY.PEEK are the only two FETCH args that have a []

This is both closer to what was requested, and much easier to parse (IMO).

Thoughts?  (I'm happy to write a patch, but there doesn't seem much point if
people don't agree).
