You could also install a "wrapok_hook" function that returns false, as 
per the below.

===========================================================================
Buffer-local Hooks
===========================================================================

Buffer-local hooks are hooks that are defined on a buffer-by-buffer
basis.  These hooks are associated with the current buffer via the
function set_buffer_hook'.  The syntax for this function is

    set_buffer_hook (name_of_hook, &hook_function);
    
Here name_of_hook is a string that indicates the name of the hook that
is being set.  The second argument, hook_function' specifies the
S-Lang function to be associated with the hook.  The calling syntax of
the hook function varies with the hook.

The following buffer-local hooks are supported:

[snip]

 "wrapok_hook"
     This hook may be used to enable automatic wrapping on a
     line-by-line basis.  Jed will call this hook prior to wrapping a
     line, and if it returns a non-zero value, the line will be
     wrapped.  See lib/slmode.sl for an example of its use.
