This is somewhat tricky to work out, so put some example code here for future reference. The tricky part is that GtkAccelLabel tries to be smart about hiding the accel if there's not enough space, so we have to make sure to pack the label with expand=TRUE and set align=GTK_ALIGN_FILL, or things won't work.
