fixes #24773
`c.inheritancePenalty` is supposed to be used for the entire match, but
in these places the inheritance penalty of a single argument overrides
the entire match penalty. The `+ ord(c.inheritancePenalty < 0)` is
copied from other places that use the same idiom, the intent is that the
existing penalty changes from -1 to 0 first to mark that it participates
in inheritance before adding the inheritance depth.
