Applied, thanks!

But I had to re-export the patch to get the \r\n line endings back, the reason
for that is that you did not explicitly passed `--transfer-encoding=base64` to
git send-email as the "auto" default value is seemingly not smart enough to go
for that encoding when it sees such line endings..

btw. you git note suggested to me that you tried this on PVE 9, but you
at least did not try to build there, as I had to fix a bit of stuff (mostly
python 3.13 related).
