Before that PR, processCommand() did not notice that cmd could be a module command in which case getkeys_proc member has a different meaning. The outcome was that a module command which doesn't take any key names in its arguments (similar to SLOWLOG) would be handled as if it might have key name arguments (similar to MEMORY), would consider cluster redirect but will end up with 0 keys after an excessive call to getKeysFromCommand, and eventually do the right thing.
