/**
 * 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.
