Well, I have serious doubts about this patch in the first place.

I think it is simply unneeded.

If you want pack-objects not to change the sort order because you have some sorting of your own, externally implemented, then you simply have to run git-pack-objects feeding it the list of object SHA1s along with a tag of your own which will effectively impose the sorting you want, based on that tag.

Objects with the same tag will still be sorted amongst themselves which is still a good thing.

for example, you may have something like:

	git rev-list --all --objects |
	sed -e 's|foo/logs/.*|LOGS|' |
	git pack-objects ...

This will effectively cluster all foo/logs/* files together for delta compression regardless of their actual name. Maybe that's what you really want?
