Each substitute can have multiple variants due to multiple applicable suggestions

foo.bar might be replaced with a.b or x.y by replacing foo and bar on their own:

vec![
    Substitution { parts: vec![(0..3, "a"), (4..7, "b")] },
    Substitution { parts: vec![(0..3, "x"), (4..7, "y")] },
]

or by replacing the entire span:

vec![
    Substitution { parts: vec![(0..7, "a.b")] },
    Substitution { parts: vec![(0..7, "x.y")] },
]

msg: String
