I think the reason we have this issue is that people tend to use
high OIDs during development of a patch, so that their elbows won't
be joggled by unrelated changes.  Then sometimes they forget to
renumber them down before committing.  A warning like this would
lead to lots of noise during the development stage, which nobody
would thank us for.  If we could find a way to notice this only
when we were about to commit, it'd be good .. but I don't have an
idea about a nice way to do that.  (No, I don't want a commit hook
on gitmaster; that's warning too late, which is not better.)
