That is a fair point.  However, sending code as an attachment is (I'd
hazard a guess) well-supported by most email programs.

More to the point in this case, it would avoid the problem of typing code
into a mail program which fervently believes the user is typing HTML code,
and tries to be "helpful" by converting strings of N>1 spaces into N-1
unbreakable spaces followed by 1 space.

(It would seem Thunderbird does this for at least some configurations, and
I'll bet that some other mail programs are equally annoying.)
