It a bit confusingly worded, and I've now installed the following phrase
instead:

"If called interactively, a numeric prefix argument specifies N, and
KILLFLAG is also set if a prefix argument is used."

While these functions are just supposed to be used interactively, they
can be used non-interactively, so I think it's right to call out the "if
called interactively" here, too.
