 It's a common convention among command-line programs that if the
 documentation describes short options, such as `-c` and `-d` then it
 should also accept their combination like `-cd`, unless otherwise stated.

 Alternatively, if this is not supported, then at least a warning abound
 unknown option "cd" should be displayed.
 Instead the process silently accepts `-cd`, and produces a colorful chart
 (-c) but does not sort by variance (ignores d).

 I'm not sure what version of hp2ps I use, because it seems to ignore
 `--version` and `-v` and `--help` does not produce version string
 anywhere.

 However:
