I'm trying to evaluate Upsource and am noticing that diffs for reviews are often noisier than expected. Roughly speaking we follow the GitFlow workflow with master/develop/feature branches. It's pretty common for developers to back merge develop numerous times over the course of developing a feature to pro-actively avoid merge conflicts. I've noticed that for reviews of branches that have done this... files that were merged in from our develop branch, often but not always, show up in the Review diff. Previously we used Stash, which uses this approach to diffing: https://developer.atlassian.com/blog/2015/01/a-better-pull-request/. This was rock solid and the behavior I was expecting from Upsource. Can y'all explain to me why I would be seeing so many files unrelated to changes on a branch in a Review?
