Just as for the previous patch:
This is incorrect as it should be surrounded by `` similar to other lines.
Otherwise it will not be taken into account by convert_misra_doc.py which converts this document into cppcheck rule list.

OK. I'll add a link to the base directory like I did in the other patch

The plans to possibly use _Generic, as mentioned during the discussion,
are (I think) making this the first case where we accept a rule with
the expectation to later break (deviate) it. I don't think I'm aware of
provisions in this regard, so by accepting the rule in the form you
suggest may well lead to people later pointing here and say "no" to any
attempt to use _Generic. IOW I think it wants clarifying in the text at
the top of the file that there is flexibility to change in how far we
mean to comply to already accepted rules.

I'll do both things:
- expand the comment in the Notes section of 1.4
- also add a comment at the top of the file
