+       * src/devices/gropdf/gropdf.pl: Comment out line causing
+       incorrect table of contents relocation.

+       [gropdf]: Fix inclusion of PDF v1.7 files.
+
+       PDF 1.5 introduced the object type ObjStm, which can contain a
+       bunch of objects in its own compressed stream, but there is a
+       restriction that an object with its own stream cannot be
+       included into the ObjStm (i.e., no streams within streams).
+       Gropdf has supported this for some years, but it has come to
+       light that some PDFs have a "skeleton" object that contains the
+       stream, while the rest of the object is held in an ObjStm.
+
+       * src/devices/gropdf/gropdf.pl: If a skeleton object exists at
+       the top level and in an ObjStm stream, merge the two objects.

+
+       * src/devices/gropdf/gropdf.pl (subs_call): Fix bad fix for
+       Savannah #65112.
+
+       {Problem introduced by me in commit 6e45bb0bc6, 4 January, when
+       I manually merged Deri's patch that wouldn't merge
+       automatically, and I misread the magic constant "16" as "6".  My
+       fault, but this is also one reason symbolic constants with
+       human-readable names are usually preferred to numeric literals.
