Comment:
It seems my change was naïve, and doesn't work on the cross-compile builds.

Kopia doesn't provide completions in the build output, but instead requires running the binary itself with a flag as [shown here](https://github.com/alecthomas/kingpin/tree/v2.2.6#bashzsh-shell-completion) in the README of the library it uses for CLI arg parsing.

Can this be done somehow within xbps or should it be fixed upstream?
