I agree with you that something ought to be done to prevent this from happening, although I'm not sure disabling code wrap is the correct thing to do. What if the line is really huge and devoid of any whitespace?

Perhaps a better solution is to add preceding and trailing newlines to code sections that are longer than the wrap length to force them start at /^/m and end at /$/m. Or maybe only do this if they contain insufficient whitespace to wrap normally.. dunno..

OTOH, you can write very long unwrappable pieces of text outside a code block too; so I guess turning off code wrapping in these cases isn't that bad
