yeppers, accelerator changes to fix the gimp.
commit message dedicated to sopwith ;)

Thu Jun 18 03:30:06 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkaccellabel.h:
        * gtk/gtkaccellabel.c: new function gtk_accel_label_accelerator_width to
        request the size of the accelerator portion of an accel label.
        (gtk_accel_label_size_request): don't request for the accelerators size.
        (gtk_accel_label_expose_event): only draw the accelerator if we got
        enough extra space.

        * gtk/gtkmenuitem.c (gtk_menu_item_size_request): request accelerator
        width from children.

        * gtk/gtkmenu.c (gtk_menu_key_press): when adding an accelerator to an
        object (after removal has been requested) check if there is still an
        accelerator remaining to avoid adding two accelerators on an object.
        this can happen for locked accelerators (or accelerator-frozen widgets).
        (gtk_menu_size_request): feature childrens accelerator width in size
        requests.

        * gtk/gtknotebook.c (gtk_notebook_menu_item_create): use
        gtk_widget_freeze_accelerators() for dynamically created menu items.

        * gtk/gtksignal.h:
        * gtk/gtksignal.c: new function gtk_signal_handler_pending_by_func()
        which will return a handler_id > 0 if the specified function is pending
        for `signal_id'.

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c: remove gtk_widget_stop_accelerator, which was just
        a signal handler function to stop accelerator addition.
        added gtk_widget_freeze_accelerators and gtk_widget_thaw_accelerators
        which will prevent (undo) any accelerators from being added to or
        removed from a widget.
