Subject: R-alpha: "convolve"

I'm having a look at "convolve" and trying to decide what it should
do.  The present version computes the "circular" convolution of the
sequences it is given as arguments, but it occurs to me that if you
don't eat discrete Fourier transforms for breakfast every morning,
this may not be the most natural result.

What should it do?  (I do plan to keep circular convolutions in some
form).
