In e61b1f76 things were changed to return string arrays that can be
freed with g_strfreev(), but that returned a one-element array
containing a NULL pointer for zero-length arrays. Fix the code
to return NULL again for zero-length arrays. See bug #751584.
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
Add the note about the need to free the returned string array
to the generated libgimp code. This way it will show up in the
libgimp documentation but not in the general PDB API.
Such comment should not be included in the general PDB
documentation as it is specific to the C bindings and can
be easily added by the pdbgen infrastructure.
This reverts commit c9888f2222.
