This isn't in itself proof that Greenwald was lying, since this requires additional knowledge of his internal mental processes, but it leaves open the possibility. I still think the phrasing in Eichenwald's tweet implies alteration, but with knowledge of the specifics of the article I agree that it can be interpreted differently.
But as 'nostrademons' points out, the current version of the article reads differently. I'll switch to a Dec 1 archive.org link in case it changes again: http://web.archive.org/web/20161201141729/http://www.newswee....
This version starts with a photo caption that includes the words "faked document". It's been changed to include the words "altered documents" multiple times. While couched in a hypothetical, it explicitly says "the Russian effort to quote an altered email". I feel certain that that the new version has been written in a manner that encourages the reader to conclude that leaked emails may have been altered and should not be considered authentic.
I don't know if these changes were made by Eichenwald or by someone else at Newsweek, but I think the post-publication changes strengthen rather than weaken Greenwald's overall claim that there as a strong media narrative to discredit the authenticity of the leaked Podesta emails. While the original article seems accurate, I find the changes that were made to it to be substantial, disingenuous, and worrisome. I'd be very interested to know how these changes came about.
It checks out, and at least on that point Eichenwald seems to be closer to the truth than Greenwald is (Greenwald hardly has anything to say in his own article about the details of the Eichenwald situation, only name-drops and sneers). It looks like this is Greenwald raising his hackles because he perceives his work with wikileaks to be under attack from Eichenwaldl.

Differences start around paragraph 6.
When I follow a link from Greenwald's piece I see this tweet that was sent by Eichenwald: "Russian gov manipulates email to @johnpodesta. Publishes disinformation. Takes it down. Trump recites false info." https://twitter.com/kurteichenwald/status/785676641880027136
I interpret "manipulates" as claiming that the emails to Podesta were changed by the Russian government before they were passed to Wikileaks. Referring to them as "disinformation" also claims that the contents of the emails have been modified. And I take "recites false info" to be reiterating once again that the emails are not genuine.
From the outside, it certainly seems that Greenwald is justified in saying that Eichenwald claimed that the emails were fake. But apart from reading this quote, I'm not familiar with the details here. Could you be more specific, and specify a exact quote from Greenwald that you feel is deliberately distorted, and a corresponding quote from Eichenwald that shows the undistorted truth?
