Make new (minor) release
The latest version of pt_BR and tr translations from Translation project were not added before the latest xdg-user-dirs (0.17) was released. This can be identified by looking at 0.17.0 tag which links to ec015cdd, a commit before pt_BR and tr being committed.
Don't know about 'tr', but pt_BR had directory name fixes that I was expecting to see applied, but they are still wrong.
Please make a minor release, like 0.17.1, that includes later commits (and any other new translation from Translation Project, if any).
