merge request .patch and .diff links get hyperlinked unexpectedly

so, there's some (undocumented?) feature that likely came from github, that if you append .patch or .diff to merge request url you can download the changes of each commit suitable for git am or just differences from base branch as single chunk.

however, if you paste such link to commenting area, it makes only merge request as link:

• https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28202.patch
• https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28202.diff

the expected outcome is to at least include .patch or .diff in link as well

for example existing extra links are rendered as:

• diffs: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28202/diffs
• pipelines: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28202/pipelines
• commits: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28202/commits

note pipelines handled differently than diffs and commits and i think should be also displayed as pipelines: !28202 (pipelines)
