The same two values are also in `~/.config/go/env` (`dot_config/go/env.tmpl`), Go's own config file, so every `go` invocation uses them even without these variables (cron, `sudo -u`, `env -i`, GUI apps).

Repos with the same name under different owners become `<owner>-<repo>`. Links pointing into `~/Code` whose repo is gone are removed; real files, real directories, and links pointing elsewhere in `~/Projects` are never touched.
