@Umberto73 basically he wants you to resolve conflicts (with latest head) and squash all commits so it would look like 1

I've resolved the conflicts and committed them. Please verify.

@Umberto73 looks like this never made it into the repo. I'm having this problem, so it would be great to see it resolved!

@dsmurfin Thanks for bringing this back up! Will take a look.

Hi @chrisballinger it appears GitHub actions has closed this again! This definitely needs to be resolved as it's a bit of a flaw, but I don't have the time at present to put in a pull request myself.
