Fix a curses bug exposed by the ":numbers" display of systat -iostat.
This bug showed up when you had more than 3 devices displayed. (thus
requiring a second line of display)
Here's a quote From the PR:
When wrefresh() is called with a subwindow as argument, __set_subwin
might be called with reversed arguments if wrefresh() decides to calls
quickch(). This may cause use of negative array indexes, with a
resulting segfault.
Since quickch() manipulates the line structures belonging to curscr,
it looks like all subwindows of curscr should be updated.
