CWG2586 Explicit object parameter for assignment and comparison

[jensmaurer]

See CWG2586.

It's pretty obvious that the situation for comparison operators is a wording oversight, but it's less obvious whether the relaxation of the rules is desirable for copy/move assignment operators, since those are a lot more restricted in the status quo (they can't be friends, for example).
