Bug description: bitwise operators return different lengths
Description:
------------
If a biwise operator is applied on strings with different lengths one
would expect that all such operators would return a string which length is
a maximum of the lengths of the operands. Or at least that OR and XOR would
do that.
But neither is true since OR returns string having the maximum of both
lengths and AND, XOR the minimum.
That's why I think there is a bug in ^ operator.
& operator may behave in both ways, although I would prefer the same
behavior as in the case of | and ^.
Reproduce code:
---------------
echo bin2hex("\x01\x02" & "\x01\x00\x01\x02"),"\n";
echo bin2hex("\x01\x02" | "\x10\x20\x10\x00"),"\n";
echo bin2hex("\x01\x02" ^ "\x00\x00\x00\x01"),"\n";
Expected result:
----------------
01000000
11221000
01020001
-- or --
0100
11221000
01020001
Actual result:
--------------
0100
11221000
0102
