Subject: 24.0.92;
	pcmpl-ssh-known-hosts - parse hosts with non-standard port numbers
Date: Tue, 17 Jan 2012 08:16:30 -0500

This patch extends the regex in pcmpl-ssh-known-hosts to include hosts
that use a non-standard port number.

The description of this syntax in the sshd(8) man page is:
A hostname or address may optionally be enclosed within `[' and `]'
brackets then followed by `:' and a non-standard port number.

Patch:
