All tags without usage

[timmyomahony]

I might be missing something here, but the only way I can see to list all tags throughout the entire system is:

tag --usage

This lists all tags with their associated usage

I want to use tag to get all available tags for a script in Alfred. It's easy enough to split the output of tag --usage but it would be useful to just have a simple command that outputs all tags on their own. I've tried tag --list but this seems to list folders as well.
