[PATCH] Allow matching HostName against Host entries

[Alan Barrett]

I would find the proposed MatchHostName feature very useful.  It 
would allow me to remove a significant amount of duplication from 
my ssh config files.

Sure.  The admin should not put "MatchHostname yes" in the system ssh
config file; it's something that users should be able to choose to put
in their own config files.

You could always override with "MatchHostName no", like this:

     MatchHostName yes # global setting

     host foo
       user  specialaccount
       hostname foo.bar.com
       MatchHostName no # override for "host foo"

     host *.bar.com
       user normaluser
       SomeOtherSetting "used for 'foo.bar.com', but not used for 'foo'"
