Modified ^W in string (and file name) arguments: ensure that we always rub out beyond empty arguments

 * it was annoying not to be able to rub out anything with ^W if the current string
   argument was empty.
 * Now, the special file name and string argument handling for ^W is effective
   only if the current argument is non-empty, else we fall back to the rub-out-command
   behaviour.
 * So now, if you press ^W in a string argument, it is rubbed out until empty and
   on the next ^W press, the entire command will be rubbed out.
