That's a good point. However, since I think newTLI is already in use
in some of the functions StartupXLOG() calls, and since I think it
would be good to use the same name in StartupXLOG() as in the
functions that it calls, what I'd prefer to do is rename the newTLI
variable in the inner scope to newReplayTLI, as in the attached v2.
