Notes

* Only the window data from window win is written to a file, not the entire screen.

* My default terminal setting shows orange text (as you see throughout this site). That's because I was fond of amber monitors back in the day. Still, the standard screen output for this code is white text. That's probably an effect of the start_color() function; though a color pair isn't initialized for the standard screen, I believe start_color() resets the terminal defaults.
