Your problem is that no change made to the environment variables of a
subprocess can affect the environment variables of an ancestor process.

This is why most of us make sure our TERM environment variable is properly
set up by a file that is SOURCED, not executed in a subprocess, when our
shell starts up (e.g. .profile or .login).
