 * Lisp Changes in Emacs 21.3
 
+** 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.
+
+Thus, point can go before an invisible, intangible region, but not
+after it.  This prevents C-f and C-b from appearing to stand still on
+the screen.

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

+        * simple.el (line-move-invisible): New subroutine.
+        (line-move-to-column): New subroutine--smarter about advancing over
+        invisible parts of a line, or lines, but only as long as hpos grows.
+        (line-move-finish): New subroutine: repeatedly processes desired
+        column, intangibility, and fields.
+        (line-move): Use those subroutines.
+        When moving lines downward, skip invisible text first rather than last.
