For some reason, /play -c seems to demand a target window or nickname, when none should be needed.
Should work but doesn't: /play -c file.txt
Should work but doesn't: /play -c file.txt 1000
Specifying an arbitrary target parameter seems to work, but it's weird. Example uses a hyphen.
Works but seems weird: /play -c - file.txt

Understandably a target would be useful if context sensitive commands like "/say" or "/me" are used.
So targets should be allowable, but not mandatory.
