Kristian Rietveld 3c09d348d3 move insert_text and delete_text virtual functions to do_insert_text and
Wed Oct  3 23:47:25  Kristian Rietveld  <kristian@planet.nl>

        * gtk/gtkeditable.[ch]: move insert_text and delete_text virtual
        functions to do_insert_text and do_delete_text, add signals
        insert_text, delete_text and changed

        * gtk/gtkentry.[ch]: remove signals insert_text, delete_text
        and changed. Updates to match new situation.

        * gtk/gtkspinbutton.c: updates to match new situation

        * gtk/gtkoldeditable.h: remove signals changed, insert_text
        and delete_text

        * gtk/gtkoldeditable.c: updates to match new situation

        * gtk/gtktext.c: updates to match new situation

        Fixes bug #59803
