To be clear, and to _repeat_: _THIS_ bug is about the quoting of
_these particular terms_: whether they should be quoted (and why),
and if so, whether (and why) they should be changed to lowercase.

The bug Subject line indicates that I even mistakenly interpreted
these terms as intended to be Lisp strings, so much was it unclear
to me what these quotations are all about.  These are not the
usual terms ("UNIX", "DOS", and "Mac").
