The long-term ideal is for the Perl filter to be able to specify the list
of headers that it wants, or all if it wants all of them, and for INN to
satisfy that request.  Just providing all of them may not be too hard,
though, although one thing to be aware of is what to do with repeated
headers.

Basically, INN's internal header parsing would need to be decoupled from
the code that loads the headers into a hash for Perl.
