value for "[ ]==[ }"

[Jun Ohta]

Hello,

I have noticed a difference between versions 2.1.50 and 2.1.70 on cygwin.
-----------------------
In the version 2.1.50, 
>> [ ] == [ ]
ans = 1
>> 
-----------------------
In the version 2.1.70
>> [ ]==[ ]
ans = []
>> 
-----------------------
The value for "[ ] == -1" is different between these 2 versions, too.

Are these differences intentional?
These differences are important for my scripts, where I use "[ ]" (return) as a 
reply 
value for question by the function "input". 
 
I would appreciate any comment.
