I like to have a clean commit history. When I address pull request comments, I won't do so by using an additional commit but instead amend an existing commit. This keeps the history from having hundreds of "addressing PR comments" commits. However, when doing this reviewers don't easily know what I have changed Stash will say I "updated the pull request by adding 1 commit and removing 1 commit." Reviewers then have to either try to parse what has changed between these two commits or review the entire file again. It would be great if Stash would show a diff between these two commits.
