I don't see that. Maybe give a concrete example. What I see is that whitespace
is either ignored everywhere or it is not ignored at all (toggle this with
`##').

Are you sure that the paragraphs themselves have only whitespace differences?
You say that `;;;' is highlighted as different. Do you mean that the `;;;' is
highlighted in both of these identical lines?
;;; commented line
;;; commented line

I've never played with that, and I don't know of any command or option that
helps here, but maybe someone else can help. Looking in the code a bit, I see
this:
1. Those are defvars, not defcustoms.
2. They are buffer-local.
So I tried this in each of two buffers that had only this, respectively:
"2011-01-01" and "2011-01-02": `M-: (setq ediff-word-1 "[:word]")'.
Then, hitting `!' showed a refinement that distinguished "2011" from the rest.
I would have expected the "01" / "02" difference to be distinguished. Maybe you
can play around a little more this way to get what you want.
