I still don't quite understand this.  When I use Emacs, in, say,
C Mode, typing normally lines things up.  Pressing return adds a
newline and indents the current line, and the only thing that
changes indentation is if I forget a close ";", or add an open
or close brace ("{" or "}").  But perhaps I misunderstand your
needs.

So, you don't want transient-mark-mode?  I don't believe that it
is turned on by default.  Certainly, without any kind of
customisations (emacs -q --no-site-file), when setting the mark,
and then moving away, the mark is not lost.  However, in this
mode, you cannot see what part of the text is marked.

Note that if you use transient-mark-mode (or zmacs-regions in
XEmacs), you can swap point and mark around by doing C-x C-x.

If I understand your needs correctly, this .emacs is probably
close to what you want:

;; turn off all major-mode associations
(setq auto-mode-alist nil)
(setq interpreter-mode-alist nil)

;; Make return indent to the current level
(global-set-key (kbd "RET") #'newline-and-indent)
;; Make tab insert a tab, always
;; If you want tabs to be converted into spaces, you

(global-set-key (kbd "TAB") #'self-insert-command)

;; Make the DEL key work the same as C-d (and not like backspace)
(global-set-key (kbd "<delete>") #'delete-char)

;;; end

kill-whole-line is nil by default, and has been since it was
first introduced in Emacs in 1993.  So, if it isn't for you, the
site file must be changing it.
The command line option to inhibit site-file loading is
"--no-site-file".

Is there any particular need that you need a new Emacs version.
If, like you say, Emacs 20.7 works fine for you, and you have no
need of the new features in Emacs 21, why not stick with Emacs
20?  Or, use micro-emacs everywhere, after all, it's not an
overly large install.
