Eclipse: any way to checkout a PR for review?

[Jeanette Winzenburg]

when reviewing a PR with only a few files changed, I simply create a  
local branch and c&p the changes (*cough, pretty sure there's a better  
way, but then that's the most simple ;).

With changes to many files (like f.i.  
https://github.com/openjdk/jfx/pull/569) that still would be doable,  
but rather cumbersome - so looking for something like "gh pr checkout  
569" (not that I ever tried that, just copied from the doc :) inside  
Eclipse.

An alternative might be to fork-the-fork .. ?
