Reviewing the documentation for 7.1 release and the function
cmdline_options is not documented. I can see with
grep that there are a few places where it is used in the code, but I don’t know if these are legacy and could be removed or not.
The function also produces some strange output. Starting Octave with
octave -q --quiet
and then executing
x = cmdline_options x.argv
shows long strings with what I assume are null bytes. It doesn’t look right to my eye.
