### Summary Merge Requests don't show permissions changes on files on GitLab EE ### Steps to reproduce 1. Create a change to a project which changes a file's permissions (e.g. change a file from 0644 to 0777) and commit it to a branch. 2. View the single commit in GitLab `{project}/commit/{sha_hash}` 3. Observe the file permissions being changed. 4. Open a merge request for that branch. 5. Observe that the merge request at `{project}/merge_requests/{id]/diffs` doesn't show the permissions change. This means that code reviewers don't see the permissions change unless they individually browse through the commits. Note, viewing a single commit in the merge request still isn't sufficient. ### What is the current *bug* behavior? File permissions changes aren't visible on MRs meaning MRs merge changes containing permissions changes erroneously. ### What is the expected *correct* behavior? File permissions changes are visible, and the changes are seen by the reviewer.
