Demonstrate that Quote produces invalid Windows quoting

On Windows, Quote wraps arguments in bash-style `\"…\"` and rewrites
embedded double quotes as `"'"'"`. Neither convention is understood by
cmd.exe or CommandLineToArgvW, so commands built from quoted arguments
are mis-parsed once they contain quotes or spaces (#5560).
