Looks good! I did different test cases 👍

git remote add blackshadev [email protected]:blackshadev/dnscontrol.git
git fetch blackshadev
git checkout -b fix-quoting --track blackshadev/fix-quoting 
go build

dnscontrol preview --domains jcid.nl

So is this a good thing?

Did jcid.nl contain a fixed record and is the 0 corrections as expected. Or did you expect it to remove some quoted TXT record?

Your comment and my edit crossed paths. Fix looks good to me. I had already given a GitHub approval in advance. 👍

Thanks!
