} It does seem logical, but the code is obscure and it's not clear whether
} this was intended or not---it probably fell through the cracks.
The (P) flag was supposed to create an approximate equivalent of ksh
"nameref" parameters. Because of the way array expansion operates in
ksh and similar shells, extending (P) to an automatic "map" over an
array wasn't considered.
