Right I didn't check the other commits, that's unfortunate, perhaps the mdoc configuration is outdated. However I'd still prefer to have 1 tab without the underscores - I don't think they are a fundamental improvement because at least for now our syntax highlighting doesn't support it

Ok. If fact, mdoc look like to check with scala 2.12.4, that does not support such constant...
We just have to not use "mdoc". I will perform the change.
