This line still doesn't work for me.
curl -s https://patchwork.kernel.org/series/736654/
returns:
The page URL requested (/series/736654/) does not exist.

while
curl -s https://patchwork.kernel.org/series/736654/mbox/
returns proper mbox format.

This part completely makes sense! Would be great to converge
on common usage, but json fetch doesn't work for me for some reason.
While mbox via original -c works fine.
