Requiements like CopyConstrible and MoveAssignable are usually marked
up in code font. This PR applies the same pattern to the swappable
requirement, but not 'swappable with'. The need for this change was
most obvious for types that combined the swappble requirement with
others, such as MoveConstructible.
