IIUC if you break the chain, indeed you wouldn't be able to use `M-.` to
keep going to the next def, but you could still use `M-g M-n` for that.
The extra keyboard movement from `M-.` to `M-g M-n` is expected to be
much less of a burden since you presumably already moved your fingers
away from `M-.` to break the chain.
