Until the included-regions feature is ready, we're using excluded-regions with a negative regexp to simulate it. example: ^(?!plugins/my-plugin-0.1\/).+$

We have the git plugin building straight off a branch and are not using merge before build. The behavior I'm seeing is that if I push commits directly to that branch this works great, but if the HEAD of that branch refers to a merge commit, the build ALWAYS thinks it ought to build, even if no changes were registered that weren't excluded by the regexp.
