"For g_list_find_custom() and g_slist_find_custom() it is not documented whether
"func" is called with "data" as first or as second argument (and with the other
argument of "func" being a value from "list").

Please document it. It matters for asymmetric comparison functions like the
following:

#inlcude <sys/stat.h>
static gint
greek_word_clicked_morph_compare(gconstpointer a, gconstpointer b)
{
  int x = (struct stat*)a->st_atime;
  int y = (struct stat*)b->st_mtime;

  if(x == y) return 0;
  return x > y ? 1 : -1;
}

Note asymmetry: "atime" for the left arg, but "mtime" for the right one."
