This command is used to list user names currently on the requested
channel; either the argument <Channel ID> or the <channel name>.
One of these arguments must be present. The server MUST resolve
- the user names and send a comma (`,') separated list of user names
- on the channel. Server or router MAY resolve the names by sending
- SILC_COMMAND_WHOIS or SILC_COMMAND_IDENTIFY commands.

- name list MAY include a indication that the server could not
