Without shell=True, args as a string on POSIX is generally an error
because it will look for the entire string as the executable. The
exception is if the string has no command-line arguments (e.g.

On Windows it's always acceptable to pass args as a string. For a
complex command line it may be easier to pass args as a list and let
Popen call list2cmdline to create a string that's properly quoted and
escaped. Here 'properly' assumes the target executable parses its
command line using VC++ rules. It may use custom rules, in which case
you have to pass args as a string.
