The \code{*} (multiplication) operator yields the product of its
arguments. The arguments must either both be numbers, or one argument
-must be a plain integer and the other must be a sequence. In the
-former case, the numbers are converted to a common type and then
-multiplied together. In the latter case, sequence repetition is
+must be an integer (plain or long) and the other must be a sequence.
+In the former case, the numbers are converted to a common type and
+then multiplied together. In the latter case, sequence repetition is
performed; a negative repetition factor yields an empty sequence.
