…pythonGH-152703) Argument quoting was inadvertently disabled when imaplib was ported to Python 3 (bpo-1210 commented out the ``_checkquote()`` call, bpo-9638 then removed it), so since Python 3.0 commands failed for arguments containing protocol-sensitive characters, such as a space in a mailbox name. Quoting is restored and reimplemented per the RFC 3501 grammar, so that arguments that need quoting are escaped and quoted, while flags, sequence sets and list wildcards are left intact. For backward compatibility, an argument already enclosed in double quotes is left unchanged, so code that quotes arguments itself keeps working.
