I understand.  Try the direxpand patch.  It includes the heuristics I
referenced in

http://lists.gnu.org/archive/html/bug-bash/2011-09/msg00007.html

and explained in more detail in

http://lists.gnu.org/archive/html/bug-bash/2011-09/msg00015.html

which provide a mostly-acceptable solution to that problem.  Keep in
mind that `$' is always going to be ambiguous.
