Gmail's editor for plain text will hard wrap *some* lines at about 69
characters, but not rigidly (it seems to leave code untouched).
There's no live preview (the textarea wraps at the window width). You
just click "Send" and hope it doesn't mangle your formatting.

Also, the interface displays plain text mail with a proportional font.
Depending on your browser you can hack the CSS to use a monospace
font. I use Stylish in Firefox:
