And you're exactly correct. Now please go convince all the whingers
who think that even though because their tool found a "bad" thing
there is nothing to worry about. But that's beside the point. There
really is no point here. This whole discussion is around a gratuitous
change that has no net effect on the behavior of the system. Unless
you are talking about the original change proposal, which would have
broken certain cases.

I am advocating that the code be left as is. It works fine (for what it
is intended to do, of course) and the "corrected" change is just plain
unnecessary. It is no clearer and no less clear than the original. Leave
it alone unless there is a good reason to change it. What, are y'all
getting paid by the patch or something?
