85# The header map of a carrier, such as the one TC.Sent.carrier gives for a
86# message to send: under each name, the carrier's values of that name in
87# order (law http_headers), as bend-kit's Http.add would add them one by one,
88# with the names as the carrier spells them. The fields are put in from the
89# last, each value first among its name's, which leaves every name's values
90# in order. bend-kit writes one header line for each value.
