rfc 822 imap bug

rfc 822 imap bug

[James Cloos]

I finally was able to give gnus a test with the patch.

(I had to do it as a different user with a just a couple of IMAP
folders; my own setup creates an *imap-debug* buffer of more than one
and a half gigs during startup; a bit of a burden on a laptop whose
motherboard maxes out at one half of a gig....)

Here is an example of the output to the *Messages* buffer from that
patch:

I removed each \r and wrapped it for email.

Position 314 in the string before wrapping is the start of Biebl in the
second of the three instances of the string "Michael Biebl".

So the parsing dies inside a double-quoted string, after a space.

All of the errors occur in similar points.

The relevant lines from *imap-debug* for that message are:
