+        region to read the data from.  Here we have two different subcases:
+
+        a) data was not yet added (before the first `elf_newdata' call)
+
+        b) at least one data set is available
+
+     2. this is a section from a file/memory region.  We have to read the
+        current content in one data block if we have to.  But we don't
+        read the data until it is necessary.  So we have the subcases:
+
+        a) the section in the file has size zero (for whatever reason)
+
+        b) the data of the file is not (yet) read
+
+        c) the data is read and available.
+
+     In addition to this we have different data sets, the raw and the converted
+     data.  This distinction only exists for the data read from the file.
+     All user-added data set (all but the first when read from the file or
+     all of them for user-create sections) are the same in both formats.
+     We don't create the converted data before it is necessary.
+
+     The `data_read' element signals whether data is available in the
+     raw format.
+
+     If there is data from the file/memory region or if read one data
+     set is added the `rawdata_list_read' pointer in non-NULL and points
+     to the last filled data set.  `raw_datalist_rear' is therefore NULL
+     only if there is no data set at all.
+
+     This so far allows to distinguish all but two cases (given that the
+     `rawdata_list' and `data_list' entries are initialized to zero) is
