This reverts commit 9219d356.

Reason for revert: unfortunately this says "core,quotePath" and since it includes recipe changes, we need something that the roller can munch on :(

Original change's description:
> Use core.quotePath=false when git is listing files
> 
> This prevents git from putting quotes around some file names
> (those that have astral-plane characters) and not around others.
>
