When we're talking about find-definition, it might be already taken care 
of by find-func and tramp-archive (someone needs to test, though).

But as far as "find references" goes, we're scanning the sources with 
external programs. There is 'zgrep', but I'm not sure how to set up its 
automatic use best.

I figured that's what the screenshots were about.

A button somewhere near the end might be a good idea. I don't know -- 
it's a fairly arbitrary choice that you could start with the rest of the 
work first, get it installed, and then post a question on emacs-devel 
(or wherever) whether people want to see the button as well.
