I don't remember the exact details here, but I think we needed this so
that we would ever refresh a file that watchman told us had been

have it.
P.S. Please CC novalis@novalis.org on these emails as I don't always
check the git mailing list.
P.P.S. I am testing out using emacs to send this message, so if
it ends up screwed up, I apologize.
