Evaluate exclusion rules during traversal so we can rule out entire subtrees without traversing into them instead of enumerating them exhaustively only to find that every single file inside them matches some subtree exclusion pattern. This can be a massive time reduction on large projects that mix code- with non-code in the same directory tree. On one large game project, it reduced qgrep update time from nearly 400s down to 9s.
