To be fair, thats a problem with the way browsers render anything inside the <pre> tag. If anything, it is an example of what people should do, not force unnecessary restrictions on the way they write text. Lest you might end up with:
> This is a short paragraph that I am quoting that
> someone
> else sent to me.
Or door 3: Let bad software stay bad, use good software instead and format our text naturally. If somebody chooses to use software that can't wrap text, that's fine for them personally — but I shouldn't have to deal with their artificial limitations.
