["Brett Lymn" <blymn%netbsd.org@localhost>]

Module Name:    src
Committed By:   blymn

Modified Files:
        src/lib/libcurses: add_wchstr.c addbytes.c background.c border.c
            clrtobot.c curses.c curses_private.h delch.c erase.c newwin.c
            refresh.c

Log Message:
 * Don't redraw the background if the new background character is the
   same as the old one.  This prevents excessive redraws in some
   applications.

 * Fix bug introduced when wbkgrndset was fixed, we cannot blindly
   replace any instance of the old background character with the new one
   because some of those characters were put there by the application
   leading to display corruption.  So flag characters as background when
   they are erased and only update the flagged characters when setting
   the background.
