That will break the common sequence C-@ C-s which *should* mark the 
region from where you started to where the search completes.

The OP wants to deactivate the region if he searches after copying to 
the clipboard, not every time he does a search.

If this happens automatically when using cursor movement commands, it 
seems like a bug if it doesn't also happen when doing a search.
