Summary: imaplib: parsing INTERNALDATE

Initial Comment:
The regular expression InternalDate in imaplib does not 
match dates in which the day number is two-digit with a 
leading zero.

>From a cursory glance at the IMAP definition, this is a 
legal format, and there is at least one IMAP server that 
uses it (courier-imap).

The attached patch is for Python 2.2.2, but the problem still 
exists in 2.3a2.

This patch is not yet applied in CVS.

Piers, I assign this to you because you know the module, but
the patch is pretty simple, it's just adding a 0 to a part
of the InternalDate's re:

From: (?P<day>[ 123]
To: (?P<day>[ 0123]

This is correct, RFC 2060 allows for the date to be
"2digit", where digit includes 0.  There is no attached
patch, but I can't attach to this tracker, so I'm putting it
here in the comment (it's a one character change).  This
still exists in 2004-04-23 anon cvs.
