Nothing too exciting. Here's what I tried, in order
Mail.app (Apple) can't do it (or at least no one has posted anywhere that I could find with a plug-in or hack or preference change)
gnumail (open-source) can, but is no longer under development and has other drawbacks that make it unusable.
Thunderbird (open-source/mozilla), I am told, would work, but I found it very unpleasant for other reasons (which I can't remember at the moment.)
sweetmail (now open-source) would work, but though it runs in class, there is no carbon version planned
Revolver (free as in beer) not localized in English and doesn't seem to have line-wrap options
yahoomail (yahoo) will allow the line break to be set up to 99 - This would have worked for everything I have written so far, but I really wanted no line breaks at all. Also, I dislike web-based email interfaces.
gmail (google) is also web based and can't do it anyway.
Mailsmith (Barebones software, $100) Does the trick just perfectly. I used to use it but stopped because it stores email in a proprietary database format. I dusted it off for the purposes of *sending* emails to the nitpickers.
I didn't try any X11-based or terminal solutions because they don't interface as nicely with the rest of the workflow. I am sure there are many freeware options there.
