It's meant to pass along whatever Cache-Control it gets unmodified. If
max-stale=0 isn't forwarded properly then file a bug.

However, max-stale=0 is somewhat of an odd thing as it's the same as not
having max-stale at all: stale responses not accepted. So I guess the
code utilizes this to differentiate the three states (no max-stale,
max-stale, max-stale=NN)

What clients is sending max-stale=0 btw? Can't remember seeing it..
