189081147 MDU6SXNzdWUxODkwODExNDc= 1116 `DataArray.rename` of a coordinate array fails to rename the coordinate name of it's own coordinate 1310437 closed 0     1 2016-11-14T10:47:24Z 2016-11-15T16:18:03Z 2016-11-15T16:18:03Z CONTRIBUTOR      

The documentation of DataArray.rename states that it renames the name of the DataArray and/or associated coordinates. However, if a name happens to be simultaneously the name of the array and of a coordinate, it only renames the array. This situation particularly arises when one tries to create a renamed coordinate to use on a different (new) array/dataset, as in that case the name of the only dimension of the coordinate array is the name of the array itself.
