Hmmmm, ok, how do the symbols look in the fringe?

That is, I was thinking something like:

| LF                       RF | COMMENT
| | This is a short line.     | a short line (short symbol)
|                             | an empty line (no symbol)
| + This is a very very ver < | starts a very long line (begin symbol)
| > y long line that finish < | middle of a very long line (middle symbol)
| - s here.                   | ends a very long line (end symbol)

Where, RF means Right Fringe and LF means Left Fringe.

But it seems that David's suggestion is:

| LF                       RF | COMMENT
|   This is a short line.     | a short line
| |                           | an empty line (paragraph symbol)
|   This is a very very ver < | starts a very long line
| > y long line that finish < | middle of a very long line
|   s here.                   | ends a very long line

Well, to use whitespace package in Emacs 21 and/or 22, please, download 
it from the EmacsWiki:

http://www.emacswiki.org/cgi-bin/emacs/download/whitespace.el

This version is prepared to run in Emacs 21, 22 and 23.

Well, indeed it's less intrusive.
