Applied with mostly-but-not-entirely cosmetic adjustments.
I left array_remove throwing error for multi-dimensional arrays for
the moment, because I realized that changing the dimensionality as
I suggested would conflict with the optimization to return the original
array if there were no matches. I don't think we'd want the definition
to read "multidimensional arrays are changed to one dimension, but only
if at least one element is removed" --- that's getting a little too
weird. If anyone's really hot to make it work on multi-D arrays, we
could consider disabling that optimization; it's not clear to me that
it's worth a lot. But for now I'm willing to stick with the
throw-an-error approach.
