Describe the bug

OSS-FUZZ is unhappy with a filter that uses _nwise(0).

Note that _nwise(0) typically behaves like recurse([]), and one could argue that the def of _nwise/1
is just fine. If the current behavior is judged to be acceptable, what should be done about 68056?

To Reproduce

[1] | _nwise(0)

Expected behavior
If the current behavior is deemed unsatisfactory, how should the def be altered?
Plausible alternatives would include:

def _nwise($n):
  def n: if length <= $n then . else .[0:$n] , (.[$n:] | n) end;
  if $n <= 0 then empty
  else n
  end;

and similar alternatives, e.g. replacing empty above with a call to error.
(Since the guard is outside def n, the performance impact would be negligible.)

Additional context
Neither gojq nor jaq define _nwise/1.
