Sorry for confusing you. The above is an unrelated issue. But at least
to me it is much more important one. I would not be unhappy at all if we
did not have either %z nor %x00, but the above bugs me moderately. Also I
suspect the proper fix for that issue would involve the part in log-tree
you touched.
By the way, I think Jeff's suggestion of %x00 makes more sense than %z.
