If you replace each character in the current-display-table with
a string that is the same character plus a newline, you'll get
the first display. The second is much shorter, as all that
needs replacing are spaces and tabs, each with a newline.
There's a slight difference between GNU Emacs and the latest
versions of XEmacs for setting the display table.
This function doesn't do what you are asking about, but it does
the same thing with other characters (extended ascii characters
that the fonts I use have no characters for). You can pretty
much tell from this example how to do what you want.

If it's not too intrusive a question, why? I mean, is it to satisfy an
"Emacs can do anything" challenge, or do you want to have 40 windows side
by side in a frame, or what?
Just wondering. :-)

You can add overlays to the buffer with :before-string or
:after-string properties. Not sure if this is also possible with text
properties, though. If you need to use overlays, then you need to
move the overlays when the buffer changes...
longlines.el uses a similar mechanism to show hard newlines with the ¶
symbol. But I didn't write it, so I don't know how it is done.

I want to be able to switch between different list views of a
document. For example, one might want to look at a text document as
a list of characters, a list of words, a list of phonemes, a list
(tree) of syntactic clauses, a list of sentences, or a list of topic
sentences that link to paragraphs, etc. Characters just happen to be
the simplest.
This is part of designing a mode I call todl-mode (for TODo List).
TODL is a variation on LISP specially designed for cyborgs :). The
idea is that if you can switch between different list views and add
hyperlinks to elements of each view, you will have a very powerful
tool for processing information.
I think of it as being somewhere in between lisp-mode,
emacs-wiki-mode, and something like outline-mode. It should be
possible to implement a TODL variant for any kind of code (so
todl-mode is also something like font-lock-mode).
