Re: [PATCH 1/4] merge-recursive: silence -Wxor-used-as-pow warning

I don't overly care on the implementation either way, since it's now
hidden in the helper. I mostly chose the bit-flip to match the existing
code, but I'd be happy to change it.

I don't, either, and as a step in this series, it makes perfect
sense to keep the implementation detail the same in the new helper.

Making it more readable would be a separate issue.

Thanks.
