Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Wed Jun 22 18:18:30 2016 -0400

    Fix shrinking message list
    
        * src/main-window.c (balsa_window_new),
          (balsa_window_fix_paned): set the size of the elements of the
          main window in an idle callback instead of the window creator;
        * src/main-window.h: export the idle callback;
        * src/main.c (real_main): add the idle call.
