I don't see how it deals with terminfo strings that have delay
specifiers in them (e.g. vt100). Those delay specifiers need to be
replaced by 0 or more 'pad' characters (default is NUL, but that too
can be specified in the terminfo file).

My initial plan was to call ncurses tputs() function and pass it a
'putchar' callback that passes the output bytes to
sys.stdout.buffer.write(). I haven't gotten that working yet (it's
going to require some cytyptes magic).
