Using shell=True with an argument list is valid.

On Unix, it's seldom what you want: it will invoke /bin/sh to execute the
first argument with $1, $2, ... set from the remaining arguments.

On Windows, a list is converted to a string in the same manner regardless
of the value of the "shell" argument. Specifying shell=True causes the
command string to be executed via "cmd /c ...". This allows the "program"
to be a script, whereas shell=False requires the program to be a binary
