Exactly. (while I, at this time, won't argue which behavior is more
"correct") changing this in the first place was wrong. Changing it back
is wrong again. We have two versions out with this change. These
releases reach distributions, reach hosting companies, reach developer
machines, ... changing the behavior again causes more trouble. With a
proper heads up before 5.3.8 we might probably have reverted it there.
