Hacking decode_mode_spec in xdisp.c as mentioned earlier is much more
straightforward than trying to replicate the same effect in emacs
lisp.  XEmacs has a `column-number-start-at-one' builtin and heeds it.
If there is a genuine demand for the functionality you should propose
it to the Emacs maintainers; as demonstrated it is a simple addition.

It is controversial because presently the column and line number
displays on the modeline reflect `point' which is on a line and
between characters.  The question arises as to why a user wants Emacs
to tell fibs about column/line numbers; what is wrong with column
numbers starting at zero, and line numbers at one?
