In emails-on-push message, indicate message that individual file diff is too large
If a single file exceeded a diff limit, the previous implementation would just include the file as changed but the diff itself was not shown, leading to confusion:
Notice how the nodes.pp line shows no changes.
Diff overflow limits apply to different cases:
- The entire diff exceeds 100 files OR 5000 lines
- One single file exceeds 100 KB
Example case 2: Let's say we have a diff of 50 files, most of them under 100 KB, but one of them over that limit. In this case, the idea of gitlab-org/gitlab-ce!2705 is that GitLab should show the diff of the 49 files but omit the last one.
