blame: make sure that the last line ends in an LF

This is convenient when parsing multiple the blame of multiple files, for example: git ls-files -z --exclude-standard -- "*.[ch]" | xargs --null -n 1 git blame -p > output and then analyzing the 'output' file using a seperate script. Currently the parsing is difficult when not all files have a newline at EOF, this patch ensures that even such files have a newline at the end of the blame output.
