+
+ * xdisp.c (message2, message2_nolog): Remove functions.
+ (message3, message3_nolog): Extract nbytes and multibyteness directly
+ from the string. Change all callers.
+ (message3_nolog): Don't set message_enable_multibyte since set_message
+ will reset it anyway.
+ (message1, message1_nolog): Use message3.
+ (vmessage): Use a stack allocated buffer rather than f->message_buf.
+ (with_echo_area_buffer): Remove last two arguments. Update all callers.
+ (set_message): Drop all but the second arg, which has to be a string.
+ (set_message_1): Simplify now that we know that a1 is NULL and the
+ second arg is a string.
+ * frame.h (struct frame): Remove `message_buf' field.
+ Use glyphs_initialized_p instead.
+ (FRAME_MESSAGE_BUF): Remove macro.
+ * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
+ * lisp.h (message2, message2_nolog): Remove declarations.
+ (message3, message3_nolog): Update declarations.
+ * keyboard.c (read_char_minibuf_menu_text)
+ (read_char_minibuf_menu_width): Remove vars.
+ (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
+ to correctly handle multibyte strings.
+ * frame.c (delete_frame): Don't free message_buf any more.
+ * editfns.c (message_text, message_length): Remove vars.
+ (Fmessage_box): Don't copy the Lisp string's bytes any longer.
+ * fileio.c (auto_save_error): Use message3 instead of message2.
+ * dispnew.c (adjust_frame_message_buffer): Remove function.
