If you call copy_after(..., 0) on a log with a backlog, you get all the
backlog entries, but no backlog flag. That's invalid. You either need
the _complete_ backlog + the flag, or no backlog entries; getting only
some of them is useless information.
Make copy_after stop when it hits the tail. Callers who need the backlog
are already checking for that and copying the whole log as appropriate.
