added a comment - I'm closing this issue as too generic.
If some feature does not work due to some edge case - let's raise a bug for this, fix it and add a test verifying it.
If some feature is unclear - let's improve the wiki https://wiki.jenkins.io/display/JENKINS/Clover+Plugin
I am willing to add tests, if for no other reason than to document expected behavior.
