What's wrong with this:
(defun fresh-line (printcharfun)
"Output a newline unless already at the beginning of a line.
Value is non-nil if a newline is printed.
Do nothing and return nil if PRINTCHARFUN is a function."
(or printcharfun (setq printcharfun standard-output))
(and (not (functionp printcharfun))
(not (bolp))
(princ "\n" printcharfun)))
Andreas.
