// a separator around the constraint. The `regex` crate supports neither, so the separators are
// matched as *consuming* groups instead. Only the `constraint` named group's own offset/length
// is used for the replacement below (never group 0), so consuming the surrounding separators
// does not shift the rewrite. The single-character `|`/space/comma separators are not consumed
// by both an adjacent trailing and leading match, but Composer never packs two same-major
// constraints around a single such separator (alternatives use `||`, ranges use spaces).
