Multiple fonts in comment fields

Comments added to an issue are represented in a variable width characterset (Arial i think).
This representation is very readable for normal proza, but when you're pasting Source Code (or snippets), sql queries or the results of these queries this characterset makes is very difficult to read.

It would be nice to have the ability to use an <CODE></CODE> tag within the comment (or description) box so the representation will use a fixed width characterset (like Courier) for that specific text.
