[PATCH] Allow "ProxyCommand none" in ssh_config

I'm very sorry, I confused to follow up with your article and
the article of 'Thomas Binder <binder at arago.de>'.

I agree with this.
But your patch is against the syntax of OpenSSH configuration.
In readconf.c

   # Any configuration value is only changed the first time it is set.
   # Thus, host-specific definitions should be at the beginning of the
   # configuration file, and defaults at the end.

Thus, the order of 'none' must specified earlier and you can't reset it
to NULL at this timing.

	Host foo
		ProxyCommand	none
	Host *
		ProxyCommand	/some/command
