I was thinking of touching a pre-existing file like .git/config or
.git/description, which I was hoping would be harmless. But sounds
like that's still not desired?

Okay, I guess one approach is to only refresh the index if $objtree ==
$srctree, by passing some flag to scripts/setlocalversion from
scripts/package/Makefile. Is that what you're thinking? Feels a little
strange, but it seems it'd satisfy everyone.

Okay. I guess --no-optional-locks is a no-go then.
