NULL was returned in case of an empty last line. Every users needed to special-case this. Now it will return the expected result: char_len of 0 with one PangoLogAttr. In compute_log_attrs(), 'paragraph' will be the empty string "" with 'char_len' == 0. pango_get_log_attrs() works fine with an empty string, it will return one correct PangoLogAttr (because there is one text position for the empty string). It fixes the unit tests for gtk_text_iter_is_cursor_position(). https://bugzilla.gnome.org/show_bug.cgi?id=156164
