I could mark it as clobber, although it doesn't matter much ATM since
uv_off is not used afterwards. I'll accept a patch that does this, of
course.

It doesn't have to be marked as modified (this is called "output", not
"modified", btw) because I don't care about the end value of the loop,
I discard it anyway.
