+
+   If the slot OFFSET has a corresponding default value in
+   buffer_defaults, the index value is positive and has only one
+   nonzero bit.  When a buffer has its own local value for a slot, the
+   bit for that slot (found in the same slot in this structure) is
+   turned on in the buffer's local_flags array.
+
+   If the index value is -1, even though there may be a
+   DEFVAR_PER_BUFFER for the slot, there is no default value for it;
+   and the corresponding slot in buffer_defaults is not used.
+
+   If the index value is -2, then there is no DEFVAR_PER_BUFFER for
+   the slot, but there is a default value which is copied into each
+   new buffer.
+
+   If a slot in this structure corresponding to a DEFVAR_PER_BUFFER is
+   zero, that is a bug */
