"Invalid face reference: quote" when mousing over a link

[catern]

Expected Behavior

Mousing over a link highlights the link with no messages.

Actual Behavior

Mousing over a link spams "Invalid face reference: quote" in *Messages*

Steps to Reproduce

1. Mouse over a link

Solution

This is actually fixed on the master branch right now, by unrelated refactoring. The problematic code was:

      (when markdown-mouse-follow-link
        (setq lp (append lp '(mouse-face 'markdown-highlight-face)))
        (setq up (append up '(mouse-face 'markdown-highlight-face))))

which erroneously double-quoted markdown-highlight-face.

I make this issue just as a reference, and to suggest cutting a new release so users can get this fix.
