Using GNU, all these commands are failing:

#export C=./target/debug/coreutils
rm -f xaa in2 in3
seq 10 | tee exp-1 > xaa
ln -s xaa in2
ln xaa in3

$C split -C 6 xaa
$C split -C 6 in2
$C split -C 6 in3
$C split -C 6 - < xaa

=>

# GNU:
$C split -C 6 xaa
split: 'xaa' would overwrite input; aborting
$C split -C 6 in2
split: 'xaa' would overwrite input; aborting
$C split -C 6 in3
split: 'xaa' would overwrite input; aborting
$C split -C 6 - < xaa
split: 'xaa' would overwrite input; aborting

All these commands pass with our version.
