Sergey Organov af04d8f1a5 t4013: add tests for --diff-merges=first-parent
This new option provides essential new functionality, changing diff
output to first parent only, without changing history traversal mode,
so it deserves its own test.

As we do it, add additional test that --diff-merges=first-parent by
itself doesn't imply -p and only outputs diffs for merge commits.
