Oh yeah.  I was looking at imap4, RFC 1730, but Chuck is correct,
in the superseding RFC 2060 (imap 4.1) it singles out & as needing
to be encoded to the pair &- .

But imap2000 does not honor this.  For mailbox mail/special&name,
this fails

b2 select mail/special&-name
b2 NO SELECT failed: Can't open mailbox mail/special&-name: no such 
mailbox

I'll pose this to comp.mail.imap where Mark Crispin is.
