improvement idea of man page of strfile

[Zhang Weiwu]

another idea:

       3      A Chinese poem in Tang-dynasty style is very short, fitting in 4 
              lines. Some people find getting familiar with all famous 300 such 
              poem written in Tang-dynasty a good way to use up brain-power of 
              the days. They can display random one of them on login or use
              a random one as desktop background. In fact, there are already
              public-published fortune data files collecting them.

This one I didn't try.
