(Yes, I could pipe all these together, but seeing the intermediate files is useful for debugging.)  The only remaining problem is that I cannot figure out how to convert the Windows ellipsis character to three periods.  Windows has several special characters (e.g., left quote, right quote, right apostrophe) which is why the above script has:

# replace DOS characters with proper forms (" instead of inward quotes).
tr '\221\222\223\224\226\227' '\047\047""--'

But I cannot find any description of how to enter the ellipsis character (\205).  I read that :

sed -e 's|`$(echo "\0205")`|...|g'

should do it.  But it does not.  \0205 is not matching it.

Solution: in Excel, Replace ALT-0133 (numeric keypad) with three periods.  It then saves as periods.

So why does this not work?
$ echo '"Horrid Barbarity,"' | sed 's|"\(A-z0-9]*\),"|\1$|g'

"Horrid Barbarity,"
