[Ifeffit] Filter window shape for FT?

I've always been told that when doing Fourier filtering, the R-space window shouldn't have sharp corners.  Artemis, for instance, 
allows you
to vary this, and by default puts shoulders on the window.  I have  a user who now wants the sharp corners, claiming that it 
provides the best
filtering.  He describes this as "doing the FT in a region of R-space".  What does the Assembled Multitude think of the risk of 
effects with a rectangular window?
