[yihuang]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

q bank send-enabled only support exactly one parameter, don't support query all denoms or multiple denoms as described in the help screen.

Cosmos SDK Version

0.50

How to reproduce?

In help screen it says:

$ ./simappd q bank send-enabled --help
Query for send enabled entries that have been specifically set.

To look up one or more specific denoms, supply them as arguments to this command.
To look up all denoms, do not provide any arguments.

Usage:
  simd query bank send-enabled [denom1 ...] [flags]

But in reality:

$ ./simappd q bank send-enabled
accepts 1 arg(s), received 0
$ ./simappd q bank send-enabled denom1 denom2
accepts 1 arg(s), received 2
