Thanks for this patch. The way that the diff viewer loads everything is quite different in the 2.0 beta, and I don't think I'd like to include this feature in a minor release.
Would you be willing to redo this patch on the master branch and have it load the rest of the files dynamically instead of reloading the entire page?
(Un)paginate all files changed in diff viewer
Review Request #4711 — Created Oct. 9, 2013 and discarded
Creates a new + button on the diff viewer that allows all files to be shown if desired--that way people don't have to click through multiple pages just to see the extent of all files changed.
