I do not think this is the correct thing to do.  It is unacceptable to
force a refresh of the window for every character as this may mean, in
some very dumb terminal cases, a redraw of the screen.

SUS v2 is not clear on the expected behaviour and I, personally, don't
hold a certain other curses package as being authorative on curses
behaviour.

A peek at the Open Solaris curses code shows they perform a fflush on
the output file descriptor after the tput - I think that would be a
better solution.
