Merge branch 'tb/blame-force-read-cache-to-workaround-safe-crlf' into maint

When running "git blame $path" with unnormalized data in the index for the path, the data in the working tree was blamed, even though "git add" would not have changed what is already in the index, due to "safe crlf" that disables the line-end conversion. It has been corrected. * tb/blame-force-read-cache-to-workaround-safe-crlf: correct blame for files commited with CRLF
