Disabling ForceCommand in a Match block

I am trying to force a command for all users *except* for users in the
"wheel" group. My idea was to do the following in sshd_config:

ForceCommand /usr/bin/validate-ssh-command

Match Group wheel

But obviously this doesn't work, because ForceCommand requires an
argument. I couldn't find a way to achieve what I want.

I wrote a patch that adds a "NoForceCommand" configuration option that
removes any configured ForceCommand. This allows me to have the following:

ForceCommand /usr/bin/validate-ssh-command

Match Group wheel

Is there a better way to do this? Possibly without patching openssh?

BTW, the patch is against openssh-4.5p1.
