If you use -M to 'git format-patch' when generating a patch, it will
show that you just moved the files around the directory tree, and the
patch should be quite small and easy to email and review.

In fact, you should use that as a default for all patches, as it's now a
standard that normal patch can use to consume, I have this in my
.gitalias file:
	[alias]
		fp = format-patch -M

and just use 'git fp' all the time.

try that and see what the results are.
