Here is a patch including the change I proposed.  (Yet another thing I
noticed is the indent spaces for join_search_one_level(): that
function is called within standard_join_search(), so it would be
better to have one extra space, for consistency with others (eg,
set_base_rel_pathlists() called from make_one_rel()), but that would
be too nitpicking.)  This is more like an improvement, so I'll apply
the patch to HEAD only, if no objestions.
