fs.watch on Windows 7: Renaming/deleting a file does not emit event for original path

[jorangreef]

From: nodejs/node-v0.x-archive#8372

When renaming "a.txt" to "b.txt" I get the following events from fs.watch on Windows 7 on Parallels:

rename null
rename b.txt
change b.txt

Subsequently deleting "b.txt" just gives:

rename null

According to Ben, the null rename event is the FILE_ACTION_RENAMED_OLD_NAME event. The filename is filtered out but it's not for feature parity with inotify.
