Lines 'overflowing' into other channels

[stenno]

When PM'ing Beholder and then executing a bot trigger like !players which might return multi-line responses, the last line of the response seem to 'leak' into other channels. I /query'd Beholder, then requested !players. In my PM window, i got:

<Beholder> [hdf-us] verdeescuro [nh370] WizzyTheWeird [nh370] KrO2 [dnh] ligang [evil] eitbo [tnnt] Bartlem [tnnt] hothraxxa [tnnt] k2 [tnnt] eitronco [tnnt] desertgreg [tnnt]

In the #hardfought channel, Beholder outputs:
