From: Mike Lamb <mrlamb <at> gmail.com> To: bug-gnu-emacs <at> gnu.org 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.
