How do I avoid the line-wrap character?

How do I avoid the line-wrap character?

Salutations!

I want to be able to copy a url from a text terminal.  (Actually, I'm using
a terminal emulator that will just open the link with the appropriate
incantation.)  For long links, however, the line-wrap character gets in the
way.  I tried the tip at

http://www.emacswiki.org/emacs/LineWrap

but none of the suggested replacement characters work.  (I'm running 23.3.1
under tmux.)  I then tried shelling out to something like "less," but it
seems like there is no way to suspend emacs from full-screen.  Using M-x
shell or M-x terminal-emulator seems to leave a gap in the last column.  I
eventually ended up doing something like:

(defun show-with-tmux ()
  "Displays the region in a new tmux window using less

   Unfortunately, this is the easiest way I can think of for
   getting a string without any end-of-line continuation on my
   terminal.  I want to do this for URLs so that I can use my
   terminal program to open the link."
  (interactive)
   (let ((oldbuf (current-buffer))
         (beginning (region-beginning))
         (end (region-end))
         )
     (with-temp-file "~/tmp/toread.txt"
       (insert-buffer-substring-no-properties oldbuf beginning end))
     (call-process "tmux" nil nil nil "neww" "less ~/tmp/toread.txt")
     )
   )

To display the text with "less" in a different tmux screen.  This seems to
have a pretty inelegant feel, so I was wondering if anyone knows of a
better way.

I isolate the URL on a line by itself (if it's in a buffer that 
I don't mind messing up -- otherwise I copy it to *scratch*). 

Then I edit it so it reads

x 'long://and.complicated&url' 

Then I use M-| to feed the line to the shell. (x is my alias for the
browser executable, which either opens the browser or adds a new tab
if already open.)

Undoubtedly this can be all be put into a single function, but I've
been too lazy to do it. For now this method feels very natural,
because I use M-| for all sorts of other things anyway.

The problem is that I'm running emacs on a headless remote server.  All I
want is to display the url uninterrupted so that I can copy it into the
browser on my local machine.
