Always qualify Instance with Local or Global
Since you can't see whether you are inside a section, that's needed to even see whether this is a local or global instance.
The trouble is, we have 444 occurrences of unqualified
Instance. Can we rely on all of them being
Global? For the same reason that we should always use qualifiers,
sed cannot know whether we are inside a section.
I can do the
sed, but I'm not sure how to do the review if any of these should be
Local. Also, let's do this after merging some MRs because this will cause plenty of conflicts.
