I think I'm going to change plans here, due to my desire to also
style source code in the TUI.

GNU Source Highlight and Pygments both have ANSI terminal escape back
ends.  And, I already have code that can parse ANSI escapes and turn
them into curses calls.

My new plan for handling Windows is to generalize this ANSI escape
parser and let it be specialized to emit console calls or whatever they
are.

Maybe I'll push this patch in independently after all... not sure yet.
