Revert "Banish Zalgo"

This reverts commit 0d7db9eda0c5b2bec5f27e7782ec2ac8eb897a4c.

No Zalgo here after all. This is not necessary as it is inside
an event listener, which is inherently async.
Missing semicolon
Refactor property access
Reuse fs.watchFile instances

Should reduce possibility of event emitter warnings when many watchers
are created.
Release 0.10.7
