Right. The reason I asked is that most of our structures end up
containing pointers, so it wouldn't make sense to do the equivalent of a
memcpy on them anyways. This is just data, so I thought it might be
different. I'll implement an oidcpy function to do the work.

I'm not. The definition looks like;
struct object_id {
unsigned char sha1[20];
};
I only want it to memcpy those 20 bytes; there's no pointers or anything
to complicate it.
