  * In determining access rights for a file, file_entity_access() first checks
  * whether the user has the "bypass file access" permission. Such users have
  * unrestricted access to all files. user 1 will always pass this check.
+ *
  * Next, all implementations of hook_file_entity_access() will be called. Each
  * implementation may explicitly allow, explicitly deny, or ignore the access
  * request. If at least one module says to deny the request, it will be rejected.
  * If no modules deny the request and at least one says to allow it, the request
  * will be permitted.
+ *
  * There is no access grant system for files.
+ *
  * In file listings, the process above is followed except that
  * hook_file_entity_access() is not called on each file for performance reasons
  * and for proper functioning of the pager system. When adding a filelisting to
  * your module, be sure to use a dynamic query created by db_select()
  * and add a tag of "file_entity_access". This will allow modules dealing
  * with file access to ensure only files to which the user has access
  * are retrieved, through the use of hook_query_TAG_alter().
+ *
  * Note: Even a single module returning FILE_ENTITY_ACCESS_DENY from
  * hook_file_entity_access() will block access to the file. Therefore,
  * implementers should take care to not deny access unless they really intend to.
  * Unless a module wishes to actively deny access it should return
  * FILE_ENTITY_ACCESS_IGNORE (or simply return nothing)
  * to allow other modules to control access.
+ *
  * Stream wrappers that are considered private should implement a 'private'
  * flag equal to TRUE in hook_stream_wrappers().
