annotate Python/bltinmodule.c @ 17683:e9a4e27e8d4e legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make PyIter_Next() a little smarter (wrt its knowledge of iterator internals) so clients can be a lot dumber (wrt their knowledge).
