When running an async process, the value of `process-environment' is
lost, in 'emacs -Q' scratch buffer:

    (let ((process-environment "EDITOR=test"))
      (shell-command "env &"))

and the output is my normal environment, not the limited one. When
removing the &, it works okay. I managed to pinpoint the problem to the
call to `with-current-buffer' in simple.el:4229. As process-environment
is buffer local, it is not passed in the process buffer. This patch
fixes it but I have no idea if this is the correct way to fix it:
