Problem: Trying to match the search highlight groups to the Normal highlight for the window can fail when the message highlighting contains a fg/bg that the Normal highlight doesn't (like an error message in cmd will have ErrorMsg highlight instead of MsgArea - which is Normal in cmd.) Solution: Link the search highlight groups to an empty group in 'winhighlight' thus disabling them instead of overriding them with Normal/MsgArea/etc.
