Fix copy detection corner case

We were aborting if the copied from rev was before the cut-off limit,
rather than the copied _to_ rev. The copied from rev can be
arbitrarily old.

#!/bin/sh

mkdir a
cd a
hg init
echo a > a
hg add a
hg commit -m test -d '0 0'

# Default operation
hg clone . ../b
cd ../b
cat a
hg verify

# No update
hg clone -U . ../c
cd ../c
cat a 2>/dev/null || echo "a not present"
hg verify

# Default destination
mkdir ../d
cd ../d
hg clone ../a
cd a
hg cat a
