My suggestion would be that, since the user has just typed exit<CR> or quit<CR> then writing (on *nix) "Press [[EOFKEY]] on a blank input line to exit" (where [[EOFKEY]] is taken from tcgetattr()'s VEOF value) is sufficient, because the user will already have a blank line in front of them so the immediate instruction ("Press Ctrl-D") will work and if they bother to read further they will remember the further instruction for next time; the simpler "Press Ctrl-C to exit" should be sufficient for Windows.
