Re: smartquotes.el -- Insertion of unicode quotes in text documents

[Richard Stallman]

    ;; - C-" inserts then cycles through the fancier double quotes;

    ;; - C-' inserts then cycles through the fancier single quotes;

    ;; - Inserting four dots inserts an ellipsis character. Inserting an 
additional
    ;;   fourth dot resumes with a string of dots;

    ;; - Inserting four hyphens inserts an mdash (a long dash character), then 
an
    ;;   ndash (an inter-word dash character), and then resumes with a string of
    ;;   normal hyphens.

I can see why it is useful, but we already have a similar facility:
Quail.  What about using Quail for this?
