    Andreas> Looks like the bug was added in commit 900276502f.

Yes, get_homedir doesnʼt stick a '/' on the end, and gethomedir did.

If someone can confirm that this fixes it, I can push to master or to
emacs-27, whichever is preferred (personally I donʼt think itʼs a
major bug, but it is a regression).
