Or, to put it in a somewhat more user-friendly manner, click on the "user settings" link in the comment to which I am replying, and you will be taken to a long list of configuration options, none of which have anything to do with line-wrap or code-wrap. However, at the top of that page are links for ten or so *more* pages of settings that you can mess with. Fortunately the very first of these, "Display Settings", has the needed stuff. Within the several tables of configuration options are selections to turn off code wrap altogether, or increase the length before wrap happens. I turned off wrapping, it works for me.
