So this seemed straightforward enough and I gave it a try [3], but that
didn't work unfortunately: the five new attributes are remain empty.

I thought this might be an issue with my implementation but printf says
that meta->GetOrigin(), and the other getters, all return an empty
string.

Is there perhaps some initialization step, beyond read_main_list(), that
I have overlooked? I tried it with the following code:

  import apt_pkg
  apt_pkg.init()
  sl = apt_pkg.SourceList()
  sl.read_main_list()

  print(sl.files[0].dist)    # worked before, works now
  print(sl.files[0].origin)  # new: prints nothing, neither do others


By the way, please consider including [4] (DEB_BUILDS_OPTIONS=nodoc), or
accepting an MR if you'd like me to file one.
