Ignore my previous comment. The cp.env API is *very* subtle. If the
line is just a name, it removes the environment variable, while
"name=value" adds it. That is definitely not what I was expecting
here, so I misread how it works.

I think that is modelled after how putenv(3) is made capable of
removing an existing environment variable.
