Bit vectors are also sequences; enforce this in some CL functions. lisp/ChangeLog addition: 2010-07-24 Aidan Kehoe <kehoea@parhasard.net> * cl-extra.el (concatenate): * cl-seq.el (remove*, cl-delete-duplicates): Bit vectors are also sequences; enforce this in these functions. * cl-macs.el (concatenate): If TYPE is constant, don't inline #'concatenate, replace it by a call to the appropriate C functions.
