The "breakage" is that process-environment needs to be sometimes replaced by
(environment).  This is partly unavoidable.  Since we will have several
environments, there will need a way for external package to explicitly
request one or the other.

I don't think the disagreement is about which variables should be
terminal-local and which shouldn't.  Rather it's about what API to present
to external packages to manipulate the environment.  `process-environment'
plus `setenv' does not seem quite sufficient.
