Not only in XEmacs 21.4 and SXEmacs but also in XEmacs 21.5 and
Emacs 21, `C-M-h' works but `C-M-s' doesn't.

After all I used the pure `extent' functions of XEmacs (not
fsf-compat/overlay.el) to fix the functions that replace
the selective-display feature of Gnus.

NOTE:
XEmacs 21.4 and SXEmacs users need to have the `calendar' XEmacs
package installed, that provides the `add-to-invisibility-spec'
function in auto-autoloads.el.
