imaplib incorrectly chooses to quote some arguments.

In particular, doing "UID FETCH # BODY.PEEK[]" results
in the BODY.PEEK[] being quoted, and it should not
(according to the RFC), which means the command fails.
 This is demonstrated below.  It's possible (and
likely) that other UID FETCH arguments are incorrectly
quoted.

This occurs with anon cvs python of 16/3/04, and 2.3.3.
 Windows XP SP1.

I'm happy to provide more info if required, just let me
know.  I could try and work up a patch, but it would be
better from someone really familiar with imaplib so
that I don't screw up legitimate quoting.
