I like shelf edges to look 'sharp'. Chamfering or rounding them would
stop the paint chipping so easily, but they wouldn't look so good.

The answer is that normally the edges would be slightly rounded. It does
not need to be much, just enough to allow the paint to be able to adhere
properly. Just run a hard edge down the aris of the shelf to flatten the
corner very slightly. You won't notice it from more than a couple of
inches away after it is painted.
