LUCENE-5481: Don't run unnecessary merges in IndexWriter.forceMerge.
> IndexWriter.forceMerge may run unneeded merges
> ----------------------------------------------

> Key: LUCENE-5481
> URL: https://issues.apache.org/jira/browse/LUCENE-5481
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Adrien Grand
> Assignee: Adrien Grand

>
> I was running some tests and was surprised that {{IndexWriter.forceMerge}}
> caused the index to be merged even when the index contains a single segment
> with no deletions.
> This is due to {{MergePolicy.isMerged}} which always returns false with the
> default configuration although merge policies rely on it to know whether a
> single-segment index should be merged.
