Are there any tricks to dealing with drop-outs? If I pair someone with player 0
for the remainder of an event, will I have trouble with generating pairings?

In particular, as an extreme case, I gave a player a bye for the first three
rounds and then did 'smp 1-3' for that division. tsh then complained that
"Division D already has pairings. [ehaspair]" even though the only pairing was
that one player's byes.

Clearly this is an edge condition and would not be a real problem, as at the
start I would just give Byes to whoever was matched with Ms. Missing. Are there
any other cases where setting up Byes in advances will give the pairing commands
indigestion?
