+** The position after an invisible, intangible character
+is considered an unacceptable value for point;
+intangibility processing effectively treats the following character
+as part of the intangible region even if it is not itself intangible.

 ** Support for Mocklisp has been removed.
 
 ** The function insert-string is now obsolete.
