It's a bit curious that the previous step avoided running a separate
process and instead did "diff-tree -p" all in C, but this one does not.
I think it is because this one is outside the loop? The original,
being a scripted Porcelain, formulates a lazy and loose command
line, but you may want to tighten it up a bit if you spawn a
process. If your user happens to have a file whose name is
$orig_head..HEAD, the command line you are creating (which is
identical to the scripted version) will barf with "ambiguous
argument".
One good thing about a complete C rewrite is that it won't have an
issue like this one because you'd be working with in-core objects.
