I can think of a few ways to avoid copying callouts, each with tradeoffs:

1. Remove the alt text, so that when the user copies the code listing
nothing comes with it, but then you don't have alt text.

2. Use SyntaxHighligher with modifications to allow callouts. This
gives you syntax highlighting, line numbering, and copy, but has the
tradeoffs mentioned in my previous posting in this thread.

3. a. Put the code listing in the page twice, once formatted however
you like with callouts, syntax highlighting, line numbering, etc, and
another time completely unmodified. If JavaScript is turned on, hide
the unmodified version and show the modified version, but provide a
"Copy" button which copies the content of the unmodified version into
the clipboard
   b. Instead of a "Copy" button, use a "Raw" button/link which opens
a small window showing the unmodifed version of the listing. And
instead of putting the code listing in the page twice, put the
unmodified listing in a separate file which is loaded in a new window
when the user clicks the Raw link.

I think you could do 3.b. with no JavaScript at all.
