* subr.el (with-selected-window): Preserve the selected window's terminal's top-frame. * window.el (save-selected-window): Likewise. * frame.c (delete_frame): When selecting a frame on a different text terminal, do not alter the terminal's top-frame. * term.c (Ftty_top_frame): New function. * xdisp.c (format_mode_line_unwind_data): Record the target frame's selected window and its terminal's top-frame. (unwind_format_mode_line): Restore them. (x_consider_frame_title, display_mode_line, Fformat_mode_line): Callers changed. (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM, since tty frames can be explicitly named. (prepare_menu_bars): Likewise. Fixes: debbugs:4702
