  1. environ: Support variable names containing dots 

    This is useful for transporting arbitrary settings to applications. It
is difficult to implement because shell variable names apparently may
not contain dots, but _environment_ variables may. Solving this by
parsing the variable name with `shlex` and re-joining the tokens would
swallow whitespace and thus turn "FOO BAR=baz" into a valid
assignment. So use everything up to the assignment operator verbatim
as the variable name and only shlex the value.

Environment variables containing dots are handled fine by e.g. the `env`
command and the `subprocess` module.
