- Implemented BMediaFile::Copyright, which just calls Copyright() of the extractor. So this is just a simple pass through. - Style cleanup (mostly whitespaces) Problem is that our readers currently return the copyright of the source code, not the copyright of the MediaFile itself, like the BeBook documents. Thus, we might need to change all readers to return appropiate data or behave differently for Haiku readers. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25356 a95241bf-73f2-0310-859d-f6bbb57e9c96
