In http://docs.python.org/lib/message-objects.html, getheader doc say:

"Like getrawheader(name), but strip leading and trailing whitespace.
Internal whitespace is not stripped. The optional default argument can
be used to specify a different default to be returned when there is no
header matching name."

However, getheader is not like getrawheader. getheader return the *last*
header seen, using the message dict. getrawheader retruns the *first*
header line seen, searching through the list of parsed header lines.

The text should also note that getheader is faster and the preferred way
to get parsed headers.
