Please review this, @casey-collab.  Realize in retrospect: perhaps too much content added.  I was having fun.
No, there's a link to it.  The option was just long enough that it needed a line break.  It seems like the automated process that determines whether a file is reachable somehow breaks when the links themselves have a line break in them?  It works when I open the .md files in my browser and click the links.
