Recent changes to LuceneIndexTransformer

[Carsten Ziegeler]

After the last changes to LuceneIndexTransformer, a fragment
of the code looks like this:

                if (analyzerClassname == null)
                    analyzerClassname = this.analyzerClassname;

                String sMergeFactor =
                    atts.getValue(LUCENE_QUERY_MERGE_FACTOR_ATTRIBUTE);
                mergeFactor = this.mergeFactor;

Now, there is no local variable analyzerClassname nor mergeFactor,
so the assignments are useless. Looking at the code, I would guess
that there is something wrong with it.

Does anybody know what?

PS: Eclipse shows you some warnings on the lines so you can easily
spot the code.
