In all likelihood, we've displayed several buffers in succession in that 
other window. Or none. Doing `quit-window' there exactly once won't suffice.

So I guess this amounts to keeping a buffer-window history of everything 
that was opened from *xrefs*, and on `q', iterate through that list and, 
if the given window displays the given buffer, `quit-buffer' on it. Then 
clear the history and quit *xrefs*.

I kinda like that.
