Return a shell-escaped string from *split_command.
TODO: REMOVE THIS FUNCTION AFTER 2023-06-27.
This function is a shim for the ``shlex.join`` standard library function,
which becomes available in Python 3.8 The end-of-life date for Python 3.7
is in Jan 2023 (https://endoflife.date/python). After that point, it
would be good to delete this function and just use Py3.8's ``shlex.join``.
