This is unfortunately a real thorn in our paw, and the FSF wants us
to make sure that all new contributions are properly assigned.
I'm sorry if this is a bit of a pain, but it should be a one-time
process. In the meantime, for those who do not have a copyright
assignment in place, we can only accept contributions falling
under the "small" or "obvious" exemption.
