pep540-2.patch: Patch version 2, updated to the latest version of the PEP 540. It has no more FIXME/TODO and has more unit tests. The main change is that the strict mode doesn't use strict anymore for OS data, but keeps surrogateescape. See the PEP for the rationale (especially the "Use the strict error handler for operating system data" alternative).
