I am using Sun Common Lisp as an inferior process using run-lisp and I
am using the elisp command lisp-send-defun (M-C-X) to send input from
another buffer to Sun Common Lisp.  The problem is that
lisp-send-defun tries to read in the file "/tmp/emlispnnn" (where nnn
is the process id) and this file name has no extension. Sun Common
Lisp will only read in files with the extension ".lisp" unless the
variable *load-source-pathname-types* is modified.  lisp-send-defun
contains the line

(filename (format "/tmp/emlisp%d" (process-id (get-process "lisp"))))

It would be nice if the format was put into a variable so I could
modify it so it always writes out a temporary file with a ".lisp"
extension.
