-----------------------------------------------------------
I've attached a patch (see above hbase-732.patch). It fixes the problem of
repeating text in the output of the describe command. The problem was not
specific to the describe command, but rather to any long string that was passed
through the split() method in bin/Formatter.rb. The split() method uses Ruby's
String.splice() method, which can take 2 arguments meant to signify a starting
position and a length of the substring. There was confusion as to whether the
second argument should be the length of the substring or the ending position of
the substring.
I've also added some additional tests to bin/Formatter.rb.
The tests in bin/Formatter.rb and bin/HBase.rb all passed. Standard HBase
tests were not run, as none of the actual Java code was modified.
