What is the purpose of the fourth pin on the +5V/EXT (formerly J1/J2) block?

It's just a utility hole for perhaps connecting other power supplies, such as a 9V battery clip. I don't really supply 4 pin headers for that anymore.
In the new D2 rev of the board, I added an adjacent ground hole. I've got to redo the docs to show new boards and I'm going to put in a page on various options for powering the board.
