bug: gopass shell completion for non-first argument

[foxyseta]

Summary

The gopass shell only provides autocompletion for the very first secret path, while several commands (move, delete, ...) take more than one. I tried the fish completion, and that works properly.

Steps To Reproduce

1. gopass
2. delete foo and try to autocomplete a second secret path

Expected behavior

The second secret path is autocompleted.

Environment

• OS: Alpine Linux
• OS version: 3.21.0
• gopass Version: gopass 1.15.15 go1.23.3 linux amd64
• Installation method: Alpine Package Keeper (official distro package manager)
