Subject [jira] Commented: (LUCENE-847) Factor merge policy out of IndexWriter

I think adding that new method to MergePolicy is great!  And, just
using the same "useCompoundFile" as normal segmetns is good for
starters (and, this matches what's done today).

> If we factor the merge policy out of IndexWriter, we can make it pluggable, making it
possible for apps to choose a custom merge policy and for easier experimenting with merge
policy variants.
