Here is a simple function that is used here (for years):
(defun char-position-msg (&optional FULL)
"print position message with line number, calls `what-cursor-position'
In addition, with prefix argument, show details about that character
in *Help* buffer. See also the command `describe-char-after'."
(interactive "P")
(let ((cp (what-cursor-position FULL))
(lp (what-line)))
(message "%s %s" cp lp)))
Now the pro and con reasons.
PRO: The line number is not displayed in some (many) occasions - if
the file has long lines, when the buffer is narrowed.
CON: The line number function may be VERY time consuming for very
large buffers (depends on the machine you run Emacs on).
