Javadoc errors on StringUtils.splitPreserveAllTokens(String, char)
------------------------------------------------------------------

                 Key: LANG-277
                 URL: http://issues.apache.org/jira/browse/LANG-277
             Project: Commons Lang
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Ken Geis
            Priority: Minor


In the Javadoc for StringUtils.splitPreserveAllTokens(String, char) there are a 
couple of mistakes.  I didn't check for similar mistakes in the similar 
functions with different signatures.


StringUtils.splitPreserveAllTokens("a..b.c", '.')   = ["a", "b", "c"]

should read

StringUtils.splitPreserveAllTokens("a..b.c", '.')   = ["a", "", "b", "c"]


These two lines have the same input giving different outputs.  I think that the 
input string on the second call should be "a b c  ".

StringUtils.splitPreserveAllTokens("a b c ", ' ')   = ["a", "b", "c", ""]
StringUtils.splitPreserveAllTokens("a b c ", ' ')   = ["a", "b", "c", "", ""]
