rredis nested calls cause error .redisError(“Invalid argument”) in redisZRange()

[nachti]

Problems of redisZRange in combination with redisKeys e.g. redisZRange(redisKeys("A*Sensor")) caused by f <- match.call() in .redisCmd which takes the call from redisKeys.

I'm not sure, where to fix it. The most central way would be in .redisCmd, but then match.call has to be replaced.
