writeln/1 declared as safe in sandbox.pl

writeln/1 seems to be available also outside SWISH and I note that it is declared as safe in sandbox.pl. A leftover mistake that should be fixed?

No, it doesn't harm. But is it used? Ah, ok, I see now that it can be used
to print to the terminal. Ok, so maybe it is useful for debugging purposes.

If a predicate writes to current output, we can capture the output using
with_output_to/2.
