Confirmed. The test case now looks like this:
================================================================
mkdir etc home
mtree -c -d > ../out
mtree -d < ../out
echo $?
echo "That was the first: should be 0."
mkdir etc/temp
mtree -u -d < ../out
echo $?
echo "That was the second: should be 2."
sed -i ""  's/^\(home[ ]*\)\(.*\)$/\1ignore/' ../out
mtree -d < ../out
echo $?
echo "That was the third: should be 0."
================================================================

I think it's a real bug, and the test cases don't cover "extra" elements
at all. Now I just have to figure out the right fix.
