Re: color_set

[Heracles]

Ok, so are you saying that when you use color_set, the change applies to any
subsequent text added to any window?

If so, suppose we have the case where we invoke:

color_set(1,NULL);
wcolor_set(somewin, 3, NULL);


What would be the subsequent output for this call:
waddstr(somewin, "Which color am I");

Provided you ignore syntax errors and other such micelany.
