If you copy someone's code, the code is still theirs, and we need both
a permission from them to use it and a copyright assignment to include
that in Emacs.

If we are thinking about reimplementing those function, then the
person who is reimplementing is well advised not to look at all at the
original code, but just work from requirements or from an idea of the
implementation described by someone else.
