Word wrap / "soft" line breaks

[Sven Havemann <s.havemann@cgv.tugraz.at>]

Hi!

I would like to configure the behaviour of Emacs concerning the display 
of long lines of text.

What it does:
=============
Long lines (say 800 characters with one newline at the end) fill several 
lines in the window, but emacs treats them as one long continuous line: 
Words are broken right in the middle and continued on the next line, 
which is indicated with a small bent arrow. Navigation is possible only 
to the left and right, the up and down keys may skip a dozen lines in 
the window. The alternative is using auto-fill, but that inserts many 
newlines, and I have to re-format the paragraph whenever I change 
something in it.

What I would like it to do:
===========================
A true word wrap mode where long lines fill the width of the window, but 
complete words are put on the next line if they do not fit. Up- and 
down-keys work as expected, going down one line on the screen, and not 
one line of the file.


Any help is appreciated,
thanks in advance,
cheers,
Sven
