/**
 * Creates a job that changes permissions/ownership on several files or directories,
 * optionally recursively.
 * This version of chmod uses a KFileItemList so that it directly knows
 * what to do with the items. TODO: a version that takes a QList<QUrl>,
 * and a general job that stats each url and returns a KFileItemList.
 *
 * Note that change of ownership is only supported for local files.
 *
 * Inside directories, the "x" bits will only be changed for files that had
 * at least one "x" bit before, and for directories.
 * This emulates the behavior of chmod +X.
 *
 * @param lstItems The file items representing several files or directories.
 * @param permissions the permissions we want to set
 * @param mask the bits we are allowed to change.
 * For instance, if mask is 0077, we don't change
 * the "user" bits, only "group" and "others".
 * @param newOwner If non-empty, the new owner for the files
 * @param newGroup If non-empty, the new group for the files
 * @param recursive whether to open directories recursively
 * @param flags: We support HideProgressInfo here
 * @return The job handling the operation.
