They could be logged in start(), but at the moment the logging is in
launch(), and if we keep the semantic the same as in subprocess.Popen()
(i.e. caller provides entire environment), then that logging doesn't
know which env variables might be worth logging.

Anyway, the variables weren't logged before either, so I'll just keep
that and change to passing an env dict.
