This *should* trigger the special case:

	mkdir test-dir
	cd test-dir
	git init
	(echo -n a ; yes '' | dd count=2) > file
	git add file
	git commit -m "'a' + 1k newlines"
	(echo -n b ; yes '' | dd count=2) > file
	git add file
	git commit -m "'b' + 1k newlines"

and it all seems to work fine.

But I didn't actually check that it really triggered, this is just 
creating a 1025-byte file that has a single character and then 1024 
newlines. So when the logic removes the shared tail (all the newlines), it 
leaves a single-character newlineless buffer for diff, and no, git-blame 
didn't care, and got the right answer.
