openssh unix dev - Feb 2014 - ssh config Host case insensitive

Hi,

There seems to be an issue where a case sensitive Host entry is no
longer working after update to openssh 6.5

example entry: (was working before update)
Host MyHost
	Hostname 192.168.0.1
	Port 1234
	User root
	IdentityFile ~/.ssh/id_rsa

When issuing "ssh MyHost" the outcome is now:
ssh: Could not resolve hostname myhost: Name or service not known

When the above entry is changed to:
Host myhost, the connection works fine again.

$ ssh -V
OpenSSH_6.5p1, OpenSSL 1.0.1f 6 Jan 2014

OS: Archlinux fully up to date when sending this mail

thx

This should fix it:
