Removed my patch for the extra characters in the passwd prompt caused by
the long-standing (but now fixed in development sources) ncurses problem
now that the author has an equivalent fix.
bottom of the screen can sometimes have stray characters left behind from
the previous command. This seems to be because ncurses is ignoreing
a ``wprintw(window, "%s", " ")'' when it's in the last column of a window.
I dont know who is right, ncurses or ncftp.
This workaround also makes the code a little cleaner as a side effect. :-)
