This seems like a good idea to me too. I think we'd also want a variable 
to disable auto-enabling xclip-mode (let's call it 
"xterm-enable-xclip-fallback" and assume it defaults to t). So when 
Emacs detects it is running in Terminal.app and 
xterm-enable-xclip-fallback is set, it enables xclip-mode. In all other 
cases, no change is made.

This does still result in a user-facing behavior change: instead of 
pressing Command-c, a user would have to press Emacs' key binding, M-w 
(or C-c if cua-mode is enabled).
