Description:
------------
imap_fetchstructure method sends to server folowing query:

FETCH 375 (UID ENVELOPE BODY.PEEK[HEADER.FIELDS (Newsgroups Content-MD5 Content-Disposition Content-Language Content-Location Followup-To References)]  BODYSTRUCTURE INTERNALDATE RFC822.SIZE FLAGS)

Problem is, that the generated query has double space in 'References)]  BODYSTRUCTURE'. Many servers (eg. Exchange) after receive that query close connection immediately with message 'IMAP protocol error'.

It seems, that there's no possibility to prevent this other than update IMAP library. So, for servers with strict IMAP protocol parser, method imap_fetchstructure is completely useless. Please help!
