util.isBuffer(...) fails on 2.3.0

[pfumagalli]

Someone forgot to import Buffer in util.js:

$ node -v
v2.3.0
$ node
> util.isBuffer('foo');
TypeError: Expecting a function in instanceof check, but got undefined
    at Object.isBuffer (util.js:666:25)
    at repl:1:6
    at REPLServer.defaultEval (repl.js:154:27)
    at bound (domain.js:254:14)
    at REPLServer.runBound [as eval] (domain.js:267:12)
    at REPLServer.<anonymous> (repl.js:308:12)

    at REPLServer.Interface._onLine (readline.js:209:10)
    at REPLServer.Interface._line (readline.js:548:8)

Works fine after downgrading to 2.2.1:

$ node -v
v2.2.1
$ node
> util.isBuffer('foo');
false

Seems related to b5b8ff1

Plot twist: it is imported!

The new import seems to be causing an issue with circular dependencies. Patch pending.

Thanks for reporting the bug! It should be fixed as of d5637e6, and a release with the patch is coming out soon.
