Oh, oops. Lucky I wrote it out explicitly. I'll take another look at
the Contributing chapter, now that I know I need to use the latest git
version.

Yeah, I noticed. The above has worked for most GNU utils and similar
I've ever touched, but guix seems a bit more involved. :-)

kept in code.

Maybe this route is already mentioned in Contributing. If it isn't, it should!
