We can still provide a new > internal-complete-buffer-sans-current. If there is no equivalent of Vbuffer_alist in Lisp, then internal-complete-buffer-sans-current will produce wrong results. A comment in buffer.c says it was a Lisp variable initially: /* Alist of all buffer names vs the buffers. */ /* This used to be a variable, but is no longer, to prevent lossage due to user rplac'ing this alist or its elements. */ Lisp_Object Vbuffer_alist; Maybe then we should expose Vbuffer_alist to Lisp via a new function like `(buffer-alist)' to prevent modifying this alist, but allowing getting data from it in Lisp. This will allow implementing equivalent functionality in other related Lisp functions as well. -- Juri Linkov http://www.jurta.org/emacs/
