+        Support for ICCCM  Extended Segments in X selections:
+
+        * xselect.c <Qcompound_text_with_extensions>: New variable.
+        (syms_of_xselect): Intern and staticpro it.
+        (selection_data_to_lisp_data): Run post-read-conversion on decoded
+        selection text.
+        (lisp_data_to_selection_data): If next-selection-coding-system is
+        compound-text-with-extensions, set the type of selection to be
+        compound-text.
+
+        * xterm.h (x_encode_text): Update prototype.
+
+        * xfns.c (x_encode_text): Accept additional arg SELECTIONP; all
+        callers changed.  If SELECTIONP is non-zero, run the
+        pre-write-conversion function before encoding the selection text.
+
 2002-02-21  Kim F. Storm  <storm@cua.dk>
 
         * frame.c (syms_of_frame): Change mouse-highlight default to t.
