Equivalent ssh_config setting for "ssh -N"

Dear OpenSSH developers,

Is there an equivalent ssh_config setting for the command line option

    ssh -N ...

?

I want to connect to a server that doesn't provide an interactive
shell but allows for port forwarding only.  I'd love to configure
this into my ~/.ssh/config as follows:

    Host foo
        Hostname ...
        Port ...
        User ...
        LocalForward ...
        LocalForward ...
        LocalForward ...
        SomeSettingEquivalentToDashN yes

so I can call it via "ssh foo" instead of "ssh -N foo".

Are there good reasons not to provide such a setting?
Or, would you accept a patch that introduces such a setting?
If so, how sould this setting be named?


Regards,
Volker

Equivalent ssh_config setting for "ssh -N"

Hello Volker,

I use 

ForceCommand /bin/false

On my Debian system, /bin/false is a program that does nothing
and returns a non-zero return code (i.e. an error code).

Jack

Oops.  You wanted an ssh option - not sshd.

Sorry.

Oops.  That's -T.  From the man page, it doesn't really look like
there's an ssh_config option for -N.
