Sorry, something went wrong.
Alternative fix for numpygh-31030. This does not change that `out=None` is removed from what is passed to the ufunc, but ensures that if from the ufunc one calls the original function with the original keyword arguments, there will only be a warning about a missing `out` argument if `where!=True`.

Backport of #31045.
Alternative fix for gh-31030. This does not change that out=None is removed from what is passed to the ufunc, but ensures that if from the ufunc one calls the original function with the original keyword arguments, there will only be a warning about a missing out argument if where!=True. Hence, the net effect is that the warning introduced in gh-29813 will no longer fire if there is no risk of uninitialized output.
