Subject: [PATCH] sessprep: fix detection of unbracketed IPv6 literals.

The centralisation I did in commit e3796cb77 introduced a foolish
sense error, in which I was supposed to be treating an unbracketed
colon in CONF_hostname as separating host name from a port-number-
shaped suffix if it _was_ the only one, and instead, accidentally did
so if it _wasn't_.
