annotate Python/bltinmodule.c @ 19705:b7f6fbc087a7 legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
At Guido's suggestion, here's a new C API function, PyObject_Dir(), like __builtin__.dir(). Moved the guts from bltinmodule.c to object.c.
