The quote character syntax was issue 2931.  The change was for 2.18 but
not mentioned in the Changes file.  Single, in-word occurences of - and
_ were allowed for 2.16 already, issue 2702.  It was mentioned in
Changes at that time.  I think that some other documentation was changed
as well but am not sure how completely.

The quote syntax is a bit of an ugliness which was added for sort-of
consistency reasons.
