Multi folder bug with @ usernames

[Matt Ford <matt@dancingfrog.co.uk>]

Hi,

The following fails for me

*%INBOX:"matt@dancingfrog.co.uk"/clear@imap.1and1.co.uk:993!

that is the simplest case.  Doesn't work if you append more folders to
the multi statement either.

I have no issues when using multi folders with email accounts that do
not have an at(@) symbol in them. I'm guessing that it's something to
do with how the multi(*) parsing pushes the folder string to the rest
of the program.  Perhaps along the way the double quotes get mangled?

Sadly my emacs lisp fu is not strong enough to fix.

Happily I'm in awe of how IMAP appears to be blazing fast when using
Wanderlust!

Matt.
