        * gtk/gtktextbtree.c (_gtk_text_btree_delete): fix assertion
        failure by creating the line data, but not validating it at this
        stage. Also, remove old code related to the "bogus newline" mess
        that removed all tags from the last char in the buffer if you
        tried to delete it.
        (_gtk_text_line_data_new): put this here and prepend underscore,
        remove from gtktextlayout.c
