I don't know if this is possible for Rust (but very much suspect so...), but I think that in general we should aim to be more forgiving than not with these patterns. Because, as the history of userdiff.c shows, new keywords get introduced into these languages, and old git versions survive for a long time. If the syntax is otherwise fairly regular perhaps we don't need to hardcode the list of existing keywords?
