Yes that would have worked.  I considered something like that but
decided to just be straightforward about it with an if-statement :-).

I suppose the above allows the compiler to short-circuit the comparison
if g->changed is already set, but I can't see that as important,
performance-wise.

Ok... "getting factor 2" is good I assume :-)
