(parse822_quoted_string): Free qstr before

returning error status. Otherwise, addresses like
	"A wrong quote\" <addr@dom.ain>
hit the assert in parse822_word() and coredump.
(parse822_word_dot): Removed misleading comment.

-/* rfc822 says:
-        The local-part of an  addr-spec  in  a  mailbox  specification
-        (i.e.,  the  host's  name for the mailbox) is understood to be
-        whatever the receiving mail protocol server allows.  For exam-
-        ple,  some systems do not understand mailbox references of the
-        form "P. D. Q. Bach", but others do.
-
-        This specification treats periods (".") as lexical separators.
-        Hence,  their  presence  in  local-parts which are not quoted-
-        strings, is detected.   However,  such  occurrences  carry  NO
-        semantics.  That is, if a local-part has periods within it, an
-        address parser will divide the local-part into several tokens,
-        but  the  sequence  of  tokens will be treated as one uninter-
-        preted unit.  The sequence  will  be  re-assembled,  when  the
-        address is passed outside of the system such as to a mail pro-
-        tocol service.
+/* Some mailers do not quote personal part even if it contains dot.
+   Try to be smart about it.
