Let-binding these vars can have some annoying side effects.

So instead you should use

   (let ((inhibit-modification-hooks t)) ...)

This variable exists in Emacs since Emacs-21.  AFAICT it does not exist
in XEmacs, but that shouldn't matter since XEmacs doesn't run
before/after-change-functions upon text-property changes, IIUC.

PS: Even better would be to use `with-silent-modifications', but that's
a fairly recent addition.
