I wanted to run this by folks here to get opinions/review before 
committing.  It stems from a suggestion by Oliver Taylor in a 
thread on the Emacs Humanites mailing list (the thread is linked 
to from the commit message).

If you prefer to view this patch in the GitLab diff-browsing 
interface, it's here:
