Not that I can think of a better way offhand than what you
already mentioned, but I have to say that I am not entirely
happy with this implementation.  A really old git showed two
patches (one creation and one deletion) for "complete rewrite",
which was corrected long time ago.  I do not think we will
change the typechange output in a similar way in the future, but
relying on that level of detail feels somewhat ugly.

As you are reading from --patch-with-raw, you already know the
order of patches that will be given to you when you finished
reading the "raw" part.  The patches will come in the same
order.  So it might be possible to keep track of patches to what
path you are expecting and decide if it is part of what you are
processing at the point you process "diff --git" line.
