  42 OPT-CMD-LINE is treated like a shell string; arguments are
  43 tokenized by `split-string-and-unquote'.

  45 Normally, command buffers are reused when the same debugger is
  46 reinvoked inside a command buffer with a similar command. If we
  47 discover that the buffer has prior command-buffer information and
  48 NO-RESET is nil, then that information which may point into other
  49 buffers and source buffers which may contain marks and fringe or
  50 marginal icons is reset. See `loc-changes-clear-buffer' to clear
  51 fringe and marginal icons.
