[Ryan Lortie <desrt src gnome org>]

commit 64c1b5ce880001e23ec9ac21324237fcb21ee6b0
Author: Ryan Lortie <desrt desrt ca>

    setup_env(): remove non-environment stuff
    
    Remove code not directly related to setting up environment variables out
    of setup_env() and into separate functions (which we call directly from
    the one place where setup_env() is called).
