Reformat the readme to 80 characters

I made it using the GitHub web editor and now that I am using VS Code I can fix the formatting.

 # MarkDown Shortcut
 
-In this repository I attempt to reproduce what I think is a GitHub feature of treating a MarkDown file as a shortcut.

-I've seen in this in the Mermaid repository here https://github.com/mermaid-js/mermaid where the `CONTRIBUTING.MD`
-file is "redirecting" to a nested MarkDown file whose relative path is in the main file's content, and GitHub
-treats this file in a special way as it has a dedicated "shortcut" icon.

-Let's see if all it takes is for a file to have a relative path of another file in its body or there is more magic

-I created two shortcut files, `shortcut.md` and `shortcut2.md`, one before the destination file existed and another
-after it did, however neither of them got a special icon.

-I am starting to think this might be a Unix thing with the file having special attributes that GitHub renders the
-special icon for but no other special handling.
-This is supported by the fact that the Mermaid MarkDown shortcut file just opens its raw content like any other
-MarkDown file without doing any sort of redirecting or linkifying the content path.
