ok, well first off its a really small corner of the model so you might not see any benifit from worying about this. But I know I tend to try for perfection.. LOL

when it smooths it looks fine as you have it btw. I normaly will say that the only time to really wory about something like this is if it gives you a texture problem when smoothed, or when its smoothed and the edges are not hard enough for you. Changing what is there will afect how the smooth shapes out.

that said. on the image, I recreated it. A I lost the screen cap so I just drew them in.. you can just have the edges contenue around, B is much like what you have. and C is yet a nother way to make that all quad. You might want to try C most.
