annotate Python/errors.c @ 24866:f0dbd5b49d8a legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Streamline the fast track for CFunction calls a bit more: there was nothing special done if keyword arguments were present, so test for that earlier and fall through to the normal case if there are any. This ought to slow down CFunction calls with keyword args, but I don't care; it's a tiny (1%) improvement for pystone.
