makeFacts

Returns one or more facts describing the difference between the given expected and actual values.

Currently, that means either 2 facts (one each for expected and actual) or 1 fact with a diff-like (but much simpler) view.

In the case of 2 facts, the facts contain either the full expected and actual values or, if the values have a long prefix or suffix in common, abbreviated values with "…" at the beginning or end.
