* dispextern.h (face_tty_specified_color): New function. * term.c (turn_on_face): Don't rely on undefined behavior when assigning an out-of-range value to 'long'. Simplify test for toggling highlight. (tty_capable_p): Omit last two (unused) args. All callers changed. * term.c (tty_capable_p, tty_menu_display, tty_menu_add_selection) (read_menu_input, tty_menu_activate, tty_menu_show): * xfaces.c (x_supports_face_attributes_p) (tty_supports_face_attributes_p): Use bool for boolean. All callers changed. (tty_supports_face_attributes_p): Omit defaults for color indices; no longer needed. Simplify tail call.
