 its raw content like any other MarkDown file without doing any sort of
 redirecting or linkifying the content path.

+The hypothesis turned out to be correct, after creating a shortcut using `ln`,
+like so: `ln -s destination.md shortcut3.md`, and pushing the resulting file to
+the repository, it now shows up with the special icon and its content is the
+destination file as expected and as seen in the case of the Mermaid repository
