* Fix Buffer(array) constructor to treat array arg as an array of octets
* Disable the Buffer(array-of-strings) test, since it's not actually valid.

  Node itself behaves this way, not decoding the bytes within a quoted
  string, even if the string is 1 byte wide.

    > b = new Buffer( ['b','a','c'] )
    <Buffer 00 00 00>
    > b.toString( 'utf8' )
    '\u0000\u0000\u0000'
