exp log simplify



Hi,

According to%e_to_numlog documentation:
When |true|, |r| some rational number, and |x| some expression, 
|%e^(r*log(x))| will be simplified into |x^r|

This does not work for me:

reset()$
kill(all)$
%e_to_numlog:true;
exp(r*log(x));
radcan(exp(r*log(x)));

(%o1) true
(%o2) %e^(r*log(x))
(%o3) x^r

Could you please tell me what I am missing.
