Merge branch 'eb/mailinfo' into next

* eb/mailinfo:
  Allow in body headers beyond the in body header prefix.
  More accurately detect header lines in read_one_header_line
  In handle_body only read a line if we don't already have one.
  Refactor commit messge handling.
  Move B and Q decoding into check header.
  Make read_one_header_line return a flag not a length.
