Please, fix this! You should move in a way that it keeps the history. The way
you moved lost all the original authorship.

How do I go about doing that? I used the same process for this file that I did
for the others.

I don't know what you did. Did you move using svn or git? When I move files with
git, rietveld shows correct the history. The way it's now seems that this file
was written from scratch, but it wasn't.

Eh, it didn't even occur to me to move. I just added/deleted. Sorry about that -
I'll upload a new patch when I return from lunch.
