Fix '\ No newline...' annotation in rewrite diffs
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.
