et crashes when --prune is combined with a non existing --glob, e.g.:

$ cargo run -- --no-config --level 1 --prune --glob "main.rs" tests/data
    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
     Running `target/debug/et --no-config --level 1 --prune --glob main.rs tests/data`

Thank you. I'll be looking into this
