Details:
This is with "hg id: 38a881b8fbec".
If I start with "--no-window-system", Octave used to use some ascii art (via
gnuplot I believe).
Now I get:
>> t = linspace(0, 1, 10);
>> plot(t,sin(t))
error: max_recursion_depth exceeded
error: called from
__gnuplot_drawnow__ at line 91 column 9
In Octave 4.4.2, I get:
octave:1> t = linspace(0, 1, 10);
octave:2> plot(t,sin(t))

Probably no one really uses these sorts of things anymore but they are useful
in automated testing.

I have not bisected this yet but it must be somewhat recent (last couple
months), maybe
