Add documentation about Array#join(nil). [Bug#5915]
We talked about this and it is like following:
* maybe ary.join(nil) should always use empty string as a separator,
but it disables to specify $, as a seprator through variables.
* if nil means '', the conversion is to_s. to_s is not accepted.
* nil is a special value, so special behavior is allowed.
* use of $ variables is not recommended, so it is not worth to change
current behavior.
