Re: [PATCH v12 11/20] index-helper: use watchman to avoid refreshing index with lstat()

This looks really odd. I don't see why we would need this. It seems

I found this while re-reading the series and I have not put much time
in studying this code yet. So I may be wrong. I'll post again if I
find that it's true after some more staring.

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
modified.  We definitely were missing some invalidation if we didn't
have it.

it ends up screwed up, I apologize.
