Redis COMMAND INFO BLPOP BRPOP

Why COMMAND INFO for BLPOP differs from BRPOP? Which one is correct?

127.0.0.1:6379> command info blpop brpop
1) 1) "blpop"
   2) (integer) -3
   3) 1) write
      2) noscript
   4) (integer) 1
   5) (integer) -2
   6) (integer) 1
2) 1) "brpop"
   2) (integer) -3
   3) 1) write
      2) noscript
   4) (integer) 1
   5) (integer) 1
   6) (integer) 1

Comment From: badboy

Looks like that is actually a small bug, it should be -2 (the second to last argument) for the last key.

127.0.0.1:6379> COMMAND GETKEYS BRPOP A B C 1
1) "A"
127.0.0.1:6379> COMMAND GETKEYS BLPOP A B C 1
1) "A"
2) "B"
3) "C"
127.0.0.1:6379> 

Fix is in #2599
