take-while with n<1 behaves like (repeat 1)

Question

user=> (take-nth -1 [1 3 4]) ; hangs user=> (take 5 (take-nth -1 [5 9 14])) (1 1 1 1 1)

I understand this behavior may be intentionally undefined,
but raising the issue on IRC didn't yield an answer on whether
this is a bug or grey area.

This is probably even worse now -- i.e. likely different behavior with transducer arity.

user=> (into [] (comp (take-nth -1) (take 5)) [5 9 14]) [5 9 14]
