Hello,

I have an authentication error on a SUN pop3 server after updating to
Gnus from git 2011-05-03[1].

My problem is located in pop3-read-response, when I set debug-on-error
to t, the pop3 process buffer is the following:

#v+ Point is 66
+OK POP3 Ready mel1 000236b6

+OK Capability list follows, mate

IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS CHILDREN BINARY
UNSELECT SORT CATENATE URLAUTH LANGUAGE ESEARCH ESORT
THREAD=ORDEREDSUBJECT THREAD=REFERENCES ENABLE CONTEXT=SEARCH
CONTEXT=SORT WITHIN SASL-IR SEARCHRES XSENDER X-NETSCAPE XSERVERINFO
X-SUN-SORT ANNOTATE-EXPERIMENT-1 X-UNAUTHENTICATE X-SUN-IMAP
X-ANNOTATEMORE XUM1 AUTH=PLAIN

.

+OK USER myuser set, mate

#v-

The pop3-read-response call in pop3-user returns nil in that case and my
authentication fails.

It looks like pop3-read-response is called too fast, edebuging pop3-user
permit to have point at position 416, which is on the "+" of "+OK USER".

Maybe the pop3-read-response should be reworked to handle this?

Regards.
