I love how rietveld picks a random file to compare against when adding new
files. :)

Yeah, I'm not sure if it's rietveld or git.

I believe this is a side-effect of the similarity thinger tuned to aggressively
try to catch the equivalent of a "svn cp" when your using git.  This was done to
help preserve history in svn.  We could probably come up with a heuristic that
would cause this one to be treated like a new file addition.  @maruel would be
the guy to talk to IIRC.
