Using .exec() mutliple times on the same multi object, does not behave as README claims

[tomsun]

The README currently claims that re-running .exec() on a multi object that increments a key, is expected to increment the key once per .exec()
85b0f60#diff-04c6e90faac2675aa89e2176d2eec7d8R269
(I'm deducing that claim from the example output: // 101, 2, // 102, 3)

When trying to reproduce, my first exec() produces [ 101, 2 ] and the second produces [] (unless I add more operations to the multi object before running .exec() again).

Observed with v2.3.0

I don't mind the observed behavior; just want to make sure node_redis considers this the expected behavior - and README suggests otherwise.

Thanks for pointing this out! I was not aware, that this was supported. I removed the comment in the ready. Otherwise there would have been some downsides to re-enable this behavior and it should likely be a rare use case. If anyone feels otherwise, please feel free to comment to support re-enabling this.
