In case Tail=N parameter is requested, we need to show N lines. It does not make sense to walk backwards one by one if we can do it at once. Now, if Since=T is also provided, make sure we haven't jumped too far (before T), and if we did, move forward. The primary motivation for this was to make the code simpler. This also fixes a tiny bug in the "since" implementation.
