[Bug]: Flaggie requires --no-package-manager to add USE flags to '*/*'.

[Kangie]

kangie@monolith ~ $ flaggie --version
flaggie 0.99.8

What I did

kangie@monolith ~ $ doas flaggie --pretend '*/*' '+use::potato'                     

What I got

usage: flaggie [options] request ...
flaggie: error: +use::potato: argument incorrect for */*

What I expected

kangie@monolith ~ $ doas flaggie --pretend '*/*' '+use::potato' --no-package-manager
