Make scalar multiplication go both ways. 
Being able to do `P * s`, but not `s * P`, is slightly annoying, particularly
with longer equations when it is desired to be able to glance at the maths and
see that the code is the same.

Now either syntax is allowed.

This function is unused and untested.  It's also incorrect, since the loop
32..0 iterates over an empty range.  Remove it for now; if we need it later, it
still lives in the history.
