This seems like a good thing to add as a configuration option in the
next stable version of Artemis.  I am open to votes for what the
default value should be.  I am leaning towards either 10 or 12.

Matt, the fftf() page in the reference manual does, in fact, mention
rmax_out, but only tangentially.  Could you add its description to the
parameter list?
