mention behavior of Array#join for nested arrays [ci skip]
The current documentation for Array#join does not mention the
special treatment of nested arrays.
It says:
> Returns a string created by converting each element of the
> array to a string, separated by the given separator.
Expected behavior according to the docs would be:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-[1, 2, [:x, :y]]-b"
# because of:
[1, 2, [:x, :y]].to_s #=> "[1, 2, [:x, :y]]"
Actual behavior:
[ "a", [1, 2, [:x, :y]], "b" ].join("-") #=> "a-1-2-x-y-b"
because join is applied recursively for nested arrays.
The patch clarifies this behavior.
(Also: small markup and grammar fix.)
