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

From: Johannes Schindelin <redacted>

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.
