I don't see the distinction here if you haven't set F on the command line,
but the behavior of this line by itself is not my question.

That works, but I don't see why. I have now tried all four combinations
of these two lines (each with and without "override"). The other 3 cases
make sense to me, but this one does not. It appears that if the initial
assignment is an "override" assigment, a "normal" += is always ignored.
I'm not sure I want to call that a bug, but I would at least like to see
a warning here that a line in my Makefile is always ignored and has no
effect (and is therefore likely to be a bug).
