Description

we already detect saturating_subs done one way:

https://github.com/rust-lang/rust-clippy/blob/master/clippy_lints/src/implicit_saturating_sub.rs

I came across someone doing it another way: v.checked_sub(1).unwrap_or(v)

Thought it might be one to add into the logic. Maybe an easy one for a new person to hack on?
