pjd 3d92417062 Fix various issues in how %#T is handled:
- If precision is 0, don't print period followed by no digits.
- If precision is 0 stop printing units as soon as possible
  (eg. if we have three years and five days and precision is 0
   print only 3y5d).
- If precision is not 0, print all units (eg. 3y0d0h0m0s.00).
