Compare #708. Now the tokenization of an input line is done by the shell itself. You may quote arguments with `"..."`. Empty arguments, supplied by `""` are preserved. Spaces in between arguments are squasheds; spaces inside quotes are preserved. You cannot partially quote an argument. You must not use - `cmd "abc`, - `cmd abc"def"`, or - `cmd "abc"def`.
