Some examples in help quote command line parameters. That is system-dependent; Linux command line may accept single-qouted parameters, while on Windows, cmd.exe doesn't. Of course, it's also shell-dependent; e.g., the syntax differs between cmd.exe ad powershell (and even between different powershell versions, sigh). We need to make system variants; and also always explicitly mention, which shell that is.
