      Description

      Beeswax returns result rows as strings where the columns are separated by tab characters. ImpalaClient.fetch() splits the rows and printing functions join them again. If the output_delimiter is \t, and the row doesn't contain any special characters, then the result is exactly the same string that was fetched. As \t is the default delimiter, I think that it would be useful to create a "fast path" for this special case.
