Hello.

GtkTreePaths do not know anything about underlying model (number of
elements, ...), which means that it's always possible to obtain next
path. Whether this new path corresponds to anything inside model is
beyond the scope of path itself (you'll check this when obtaining iter
from this path). On the other hand, previous path cannot be obtained
if your current path already points to first element (the one with
index 0) and this is what gtk_tree_path_prev() reports with it's
return value.

As long as I'm able to understand you, I really don't care much;)
