One more data point if you're still having doubts. In the document that you've
linked
(http://bitsavers.informatik.uni-stuttgart.de/components/intel/8086/210912-001_iAPX_86_88_186_188_Users_Manual_1985.pdf)
go to table 1-23 on page 1-56. It clearly lists instructions 82h /1, /4, /6 and
83h /1, /4, /6 as "not used".
