* are represented by their source groups. Other logical nodes must provide FileObjects in their
* Lookup.
*
* @param nodes null (then taken from windowsystem, it may be wrong on editor tabs #66700).
* @param includingFileStatus if any activated file does not have this CVS status, an empty array
* is returned
* @param includingFolderStatus if any activated folder does not have this CVS status, an empty
* array is returned
* @param onlyCachedStatus if set to true, only cached status will be considered
* @return File [] array of activated files, or an empty array if any of examined files/folders
* does not have given status
