Subject: dtas-tl: "edit" gives sequential track IDs on new tracks

Having sequential track IDs can improve readability, so complicate
our code a bit to ensure users get nicer looking track IDs.

Followup to commit 90dcf561fd22c8a53c03d97292f86a82e74ca4a3
('Revert "dtas-tl: simplify existing addtail/addhead while we're at it"')
