indicate when previous-line/next-line scrolls the text?

Is there any way of getting similar behaviour for `previous-line`/`next-line` (`C-p`/`C-n`) when moving to the next/previous line triggers movement of the text? It would be nice to have a similar sort of indication as for the page/half-page movement. (I'm not sure what function is called when `previous-line`/`next-line` hits a 'scroll boundary'.)
