Issue with patch in a reply to a patch

[Ralf Baechle]

Hi,

since a recent upgrade of patchwork in February I've observed patchwork
misshandling patches sent as reply to another patch.  An example is

  https://patchwork.linux-mips.org/patch/15887/

where James' reply (first reply) was submitted like:

So I think something like this would be more correct. Does that fix your
problem?
