There aren't enough functions in GLib to make manipulating string arrays
easy. I find that using GPtrArray is easier if I have to actually
manipulate/combine/sort/search the string array.

To get the result of g_strsplit into a GPtrArray, I have used a simple
loop, although I'm certain that this is suboptimal. I don't have to do
it much, so it's not a performance issue for me.

  for (i=0; sarray[i]; ++i) g_ptr_array_add(parray,sarray[i]);

When I'm done manipulating the array, I get the string array back:

  /* append terminating nulls to string arrays */
  g_ptr_array_add(attributes,0);
  /* throw away GLib array bookkeeping - keep only array data */
  sarray = (gchar**)parray->pdata;
  g_ptr_array_free(parray,FALSE);
