Github user kinow commented on the issue: https://github.com/apache/commons-lang/pull/311 Perfect. So maybe it is not enforcing the 4 spaces? Haven't looked at the xml settings we have in lang in a while. So if you fixed the 2/4 spaces, we won't have any other nit-picks like this, and be able to focus on the feature. Especially since you added good docs, unit cases, and even a practical use case :-)
