Comment (by simonpj):

 OK so it looks as if I made this change just before the GHC proposals
 process kicked off.

 If you think it's desirable for record wildcards to fill-in with top-
 level, or even imported, bindings, I suggest you write a short proposal to
 advocate for it.  That way we'll get some debate.

 However, the absence of documentation of this property is bad. I'll add a
 paragraph about that anyway; we can always modify it if the GHC proposals
 process agrees a change.
