gtk3/gtk/gtkmenuitem.c
Owen Taylor 2f50a3044e commiting changes from owen: 
Mon Mar  9 20:38:15 1998  Owen Taylor  <owt1@cornell.edu>

        * gtk/gtkentry.c gtk/gtkeditable.c gtk/gtkspinbutton.c:
          Moved "activate" to editable class. Made the vfuncs in
          gtkeditable just vfuncs not signals.

        * gtkentry.[ch] gtktext.[ch]: Made behavior when pressing
          multiple buttons at once more rational.

        * gtkentry.c gtktext.c: Unified and rationalized key
          bindings. (Now are basically emacs+CUA)

        * gtktext.c:
          - Last position now always shares the property of the preceding
            character
          - Freeze the widget when inserting large amounts of text.
          - Selecting lines now selects the _whole_ line.
          - Fixed bug with displaying the cursor
          - Ctrl-Home/End now move the cursor to the _absolute home/end

        * gtkmenuitem.c: Remove necessary code out of a g_return_if_fail
