/**
* Sends input from concurrently through to commands.
*
* Input can start with a command identifier, in which case it will be sent to that specific command.
* For instance, `0:bla` will send `bla` to command at index `0`, and `server:stop` will send `stop`
* to command with name `server`.
*
* If the input doesn't start with a command identifier, it is then always sent to the default target.
