Further improvements to parsing of arguments on the MATLAB command-line

Under GNU/Linux and macOS, double-quote arguments before passing them to the
shell. In particular, this allows passing single-quotes within those arguments.

We therefore have to escape the four characters that are interpreted within
double-quoted strings in POSIX shells: \, ", $ and `

On Windows, also systematically escape the backslashes.

Also move display of arguments before escaping, so that it remains readable.

contains a space, you must surround the entire ``-D`` flag with single
