gdb/
2015-01-16  Eli Zaretskii  <eliz@gnu.org>

     * tui/tui-win.c (tui_rehighlight_all, tui_set_var_cmd): New
     functions.
     (_initialize_tui_win) <border-kind, border-mode>:
     <active-border-mode>: Use tui_set_var_cmd as the "set" function.
     * tui/tui-win.h: Add prototype for tui_rehighlight_all.
