        * gtk/gtkentry.[ch]: Add gtk_entry_set_alignment()
        to allow right-aligned entries and a "xalign"

        Steffen Gutmann)

        * gtk/gtkmisc.c (gtk_misc_class_init): Use improved
        xalign property description here too.

        * tests/testtext.c: UNDERLINE_ERROR test addition
        from Nicolas Settons' patch.
