Custom address for ABCI example app

FEATURE REQUEST

Now, if I'm not wrong, the listen address of example applications (i.e. abci-cli dummy and abci-cli counter) is equal to the default (tcp://0.0.0.0:46658).
Why don't make it settable from command line?

you should be able to use either the --addr flag or --address flag:

$ abci-cli counter -h
