headers.t error on 2.4 HEAD

[Jim Jagielski]

On HEAD of httpd-2.4, the test framework fails on headers.t:

   header: [Foo Bar] vs [Foo Bar]
   # testing : compare header Hello value
   # expected: 'Foo Bar'
   # received: 'Foo     Bar'
   not ok 3

I am guessing that this is due to the header work being
in some sort of intermediate state of development?? Or
has the test framework not yet been updated??
