OK, here's the (long) patch for the Lisp Introduction to do all that. In
lieu of a description, here's a ChangeLog entry for it:
2006-10-27 Stuart D. Herring <address@hidden>
* emacs-lisp-intro.texi (Top): remove menu entry for "Complete
(Top, Emacs Initialization): remove version reference for X
(Making Errors, Void Function, Void Variable)
(Wrong Type of Argument, debug, debug-on-entry): remove discussion
of Emacs 20 error reporting.
(else): make impossible outcome obvious.
(Review): use `emacs-major-version' instead of `emacs-version'.
(Finding More): remove discussion of old `describe-function'
(Finding More, fwd-para summary, lengths-list-file)
(lengths-list-many-files, Files List): use 22.1 instead of
21.0.100 as a dummy version number.
(mark-whole-buffer overview): use version 22 `mark-whole-buffer'.
(Body of mark-whole-buffer): update call to `push-mark'. Merge
paragraphs describing `push-mark' call to include 21 information.
(zap-to-char): remove discussion of version 19 function, and the
description of error-handling in `kill-region'. Include function
source in node. Remove "Complete zap-to-char" menu item.
(Complete zap-to-char): delete node.
(zap-to-char interactive): simplify discussion of "*" in the
interactive spec, omitting version 19 bug.
(search-forward): simplify discussion of character/string
(kill-region): merge version 21 information.
(Recursive Definition Parts): use `when' in recursive template.
(Recursion with list): remove Emacs 20 instructions.
(Recursion with list, Every, recursive-graph-body-print): use
`when' instead of `if'+`progn'.
(lengths-list-file): remove Emacs 19 commentary, old path Texinfo
(Files List): use @dots instead of ".." directory in example list.
(Simple Extension): clean up testing of Emacs version and minor
mode calls, and rewrite motivation for version-specific
(Mode Line): don't mention that :eval was new in 21.
(debug-on-entry): rewrite motivation for deliberate debugging.

too sparse, it is because mass-energy conversion has occurred during
