Unset a given SendEnv?

Hi Damien,

let me tell you where I'm coming from: I have a bunch of machines. Sometimes, localisation is incomplete or broken or messed up in a different way. Straight way would be to unset LC_* in a remote bashrc. But this sucks, because of cloud hosting, automated deployment, IaaS... you know where I'm going.

I would like to do this in .ssh/config, per host. So, my best idea would be to put something like 'export MY_VAR=' in place. This is quite close to a 'SendEnv=-FOO' idea (or 'unset' in bash terms) but adds even more flexibility.
