When a file that ends with an incomplete line is expressed as a complete rewrite with the -B option, git diff incorrectly appends the incomplete line indicator "\ No newline at end of file" after such a line, rather than writing it on a line of its own (the output codepath for normal output without -B does not have this problem). Add a LF after the incomplete line before writing the "\ No newline ..." out to fix this. Add a couple of tests to confirm that the indicator comment is generated on its own line in both plain diff and rewrite mode.
