In Dr Johnson’s Dictionary under COMMA he quotes Alexander Pope:
Comma’s and points they set exactly right.
Yes, with the greengrocer’s apostrophe!
It is true that a Google search for "+comma’s and points they set exactly right" pope produces only six hits while "commas and points they set exactly right" pope comes up with 48, but I wonder how many of those 48 have been silently corrected. Johnson’s near-contemporary quoting of the apostrophe not only suggests that it was original but implies that Johnson himself saw nothing wrong with it.
