There is indeed a 'fixes/31 commits' file under there and
it's the same text exactly as 31.atom.
So perhaps its some kind of cache checking thing?
Below I've dumped the HTTP headers I see for the atom file,
in case that sheds some light. Perhaps github tracks client IPs
and sends a 0 byte file when it thinks the client already has the
up to date file? Which would be a bit weird since repeated wgets
Just Work.

I checked file ownerships and permission bits, all seems in order.

I removed the 'fixes/31 commits' file and tried again,
same error in the log file.


Thanks for looking at this. It's not terrible and I will be interested
to see if it updates when the feed next updates.
