obsolete: display information in log if a changeset is obsolete

This changeset add a new line in default log output if a changeset is obsolete:

    obsolete:     dead

I'm not very happy about it but having something to test obsolete marker is
useful. Moreover, this should not impact anybody as normal people avec not
expected to lay obsolete marker.
