Thank you, Joe, I should have looked at the manual, which says:
The condition in an `if' statement is considered true if its value
is non-zero, and false if its value is zero. If the value of the
conditional expression in an `if' statement is a vector or a matrix, it
is considered true only if it is non-empty and _all_ of the elements
are non-zero.
