So that the user doesn't have to (push "VAR=value"), or (push "VAR="),
or know the difference between the latter and (push "VAR").
setenv is a better abstraction. In fact, if you use it, you don't even
have to know the format of process-environment.

The environment is changes as a result. It just doesn't modify the
original list, and, as such, contains duplicate values for the changed
variables.
