Add option to ReverseStringFilter to mark reversed tokens
---------------------------------------------------------

                 Key: LUCENE-1813
                 URL: https://issues.apache.org/jira/browse/LUCENE-1813
             Project: Lucene - Java
          Issue Type: Improvement
          Components: contrib/analyzers
    Affects Versions: 2.9
            Reporter: Andrzej Bialecki 
         Attachments: reverseMark.patch

This patch implements additional functionality in the filter to "mark" reversed tokens with
a special marker character (Unicode 0001). This is useful when indexing both straight and
reversed tokens (e.g. to implement efficient leading wildcards search).
