annotate Python/marshal.c @ 41970:b3900a51346b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
tokenizer.c: make coding markup work again. io.open() now takes all positional parameters (so we can conveniently call it from C code). test_tarfile.py no longer uses u"..." literals, but is otherwise still badly broken. This is a checkpoint; some more stuff now breaks.
