In the following program, I try to demonstrate the use of windows by
creating two windows next to each other. win1 is supposed to be displayed,
then win2.

But if I don't call refresh(), win1 is never displayed. Oddly enough, win2
is, though. I'm calling wrefresh() on both of them.

initscr() creates stdscr, which is initially setup to erase (so that's
a pending change).  getch() refreshes stdscr if it has pending changes
before doing anything else - so that wipes out anything that you did
with win1 or win2.  Use wgetch(win1) or wgetch(win2), as needed.
