Actually, let's undo this and keep chore: - I realise now that this was just an auto-feature for the optional is-terminal dependency. Falk Woldmann Lu (@FalkWoldmann) .

Will merge when done. Would do it myself but don't want to destroy your signature.

Thanks a lot!

I had to go ahead and make the modification myself, allowing gix (CLI) to compile without this dependency.
