Or change /etc/sshd_config on the server and enable
	PermitUserEnvironment yes

and then you can add a file on the server:
	~/.ssh/environment
that contains the envvars you want to sshd to set for incoming
connections authenticated as you, and the desired values.

Note that 'man sshd_config' warns about this option, as it can be exploited.
