Pipelined commands and MULTI/EXEC does not always return a list with answers

[behe]

Redix.pipeline and MULTI/EXEC currently returns a list when executing multiple commands but only a single answer when executing a single command. I found this quite surprising, ex:

commands = [
  ["SET", "pipe", "10"],
  ["INCR", "pipe"],
  ["GET", "pipe"]
]
Redix.pipeline(conn, commands)
=> {:ok, ["OK", 11, "11"]}

Redix.pipeline(conn, [["SET", "pipe_single", "10"]])
=> {:ok, "OK"}

Expected {:ok, ["OK"]} for last command.

Same for MULTI/EXEC:

Redix.command(conn, ["MULTI"])
=> {:ok, "OK"}
Redix.command(conn, ["INCR", "multifoo"])
=> {:ok, "QUEUED"}
Redix.command(conn, ["INCR", "multibar"])
=> {:ok, "QUEUED"}
Redix.command(conn, ["INCRBY", "multifoo", 4])
=> {:ok, "QUEUED"}
Redix.command(c, ["EXEC"])
=> {:ok, [1, 1, 5]}

Redix.command(conn, ["MULTI"])
=> {:ok, "OK"}
Redix.command(conn, ["SET", "multifoo", "10"])
=> {:ok, "QUEUED"}
Redix.command(c, ["EXEC"])
=> {:ok, "OK"}

Expected {:ok, ["OK"]} for last command.

Hey @behe, great find! I fixed this issue in d723d23 and released v0.2.1 with the fix. Just mix deps.update redix and you should be good to go :) Let me know if it works!
