annotate Python/future.c @ 18887:9b291ca6546c legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add _PyUnicode_AsDefaultEncodedString to unicodeobject.h. And remove all the extern decls in the middle of .c files. Apparently, it was excluded from the header file because it is intended for internal use by the interpreter. It's still intended for internal use and documented as such in the header file.
