I'm a bit confused, because that bug talks about adding `watchedFiles` with a bunch of extensions, but looking at `iisnode.config.template` (before my change), it doesn't have any. The bug is not linked to a specific change set, so I'm not clear what change was made to fix it.

That being said, if this feels risky, I'll leave the watchedFiles commented out, such that my change is only adding a bunch of comments.
