I'm repeating it once more so Philip may take note of it :-).

also in the latest draft is this:

   The preferred way to test whether a given header is either empty or
   absent is to combine an "exists" test and a "header" test:

           anyof (header :is "Cc" "", not exists "Cc")

this will evaluate to true for:

  Cc: someone@xxxxxxxxxxx
  Cc:

it may not be worth considering this rather degenerate case.  it seems
to me Bcc is a more likely candidate for the stated test.  however, one
way of stating the test correctly is:

  not (header :matches "Cc" "?*")

it's not much more convoluted, so I think it is worthwhile to change the
"preferred way".
