We can test that git blame gives the same result with 
core.autocrlf=input  and core.autocrlf=false, and make the test case 
look like this:

test_expect_failure 'blaming files with CRLF newlines' '
	git config core.autocrlf false &&
	printf "testcase\r\n" >crlffile &&
	git add crlffile &&
	git commit -m testcase &&
	git blame crlffile >expected &&
	git -c core.autocrlf=input blame crlffile >actual &&
	test_cmp expected actual
