Sorry for the late reply--here's something Nobu came up with on 
ruby-talk a while ago:

In your .irbrc, put this line:

IRB.conf[:PROMPT][:XMP][:RETURN] = "# => %s\n"

Then run irb using the xmp mode as Brian suggested:

$ irb --prompt-mode xmp
4
# => 4

Not exactly what you asked for, but it's still useful for copy-pasting 
from irb into ruby-talk posts!

If you want to comment out stdout lines as well as irb's output lines, 
you might try modifying the STDOUT IO object to put a # at the beginning 
of each line.

HTH.
