You might want to take a look at the way I've done it in the main Gitea binary. I'm not certain that the technique used there is definitely applicable but it shows a way of doing global options without referencing multiple files.

This technique (https://github.com/go-gitea/gitea/blob/master/main.go#L97) does not work for tea as there are no flags that are required for all commands. The mostly used flags are --login, --output and --repo but those are not used by the subcommands login and logout. That's why I think this technique is not suited for tea.

Fair enough. I'm not particularly au fait with how tea does things but saw what you were doing looked slightly similar.

This PR can IMHO be merged now as I'm done with the implementation.
After merging it I'll rebase and update #25 and #13.
