Function without_tokens 

pub fn without_tokens(
    arguments: &[OsString],
    offset: usize,
    removed: &[usize],
) -> Vec<OsString>

What: Copy arguments without the tokens at removed, which are indexes relative to offset (the index of the first region token). Why: Wrapper-only flags are deleted by position, so an equal-looking value or path stays.

In TS you’d write (pseudocode):

const kept = args.filter((_, i) => !removed.includes(i - offset));
