HierarchicalConfiguration.subset(...) misses an entry with the key equal to the
subset prefix.

Key: CONFIGURATION-295
URL: https://issues.apache.org/jira/browse/CONFIGURATION-295
Project: Commons Configuration
Issue Type: Bug
Affects Versions: 1.4
Environment: Commons configuration V1.4
Loaded configuration: An ordinary commons config XML file referring to two
property files.
Reporter: Eduard Rindt
Having a HierarchicalConfiguration with entries alike:
test.sample = subset title
test.sample.boolean = true
test.sample.int = 123456
test.sample.text = I wish it worked!
When performing subset("test.sample"), I get a configuration of only three
entries, the "subset title" value is not present (should have an empty string
key).
The behaviour is in contradiction to Javadoc of the Configuration interface
http://commons.apache.org/configuration/apidocs/org/apache/commons/configuration/Configuration.html#subset(java.lang.String)
Seems to me, that the bug is hidden in iterating the cloned configuration,
where only children of the clone are processed, but not the root itself.
