Update of /project/gsharp/cvsroot/gsharp/Flexichain In directory common-lisp.net:/tmp/cvs-serv2937

Modified Files: flexirank.lisp Log Message: Fixed a bug in the flexirank code. Or, rather, compensated for a quirk in flexichain.lisp that calls move-elements on sentinels. The best way would be to avoid this quirk, but I am not willing to modify the basic flexichain code right now.
