Whatever we do, we have to be consistent. The user-visible and
lisp-visible column-numbering have to match.
But understand that it is impossible to be consistent both with how
lines are represented and how columns are represented in Lisp.
Since (current-column) can't change, column-number-mode and
what-cursor-position have to use 0-based column numbers as well (at
least by default).
Yuck! No!
If you add in Stallmacs-compatibility, the decision is clear.
I don't care about Stallmacs compatibility, but to me it seems much
more sensible for column numbers to start at 1.
I feel strongly about this. Isn't our current behavior
obviously
totally broken? It looks like a bug, so it is a bug.
No, our current behaviour is definitely *not* totally broken.

New subject: column number starts at 1 or 0?
Hiding the truth (0-based column numbering) from the user is
unhelpful long term. fill-column, comment-column,
set-goal-column, etc. don't believe in the fictional 1-based
numbering. So the users are going to have to deal with the
reality of the 0-based numbering eventually. Whether the current
coordinate system is crocked or not is not relevant. It is
reality and at this point it is immutable without hosing code far
and wide. Best to let the users see the reality and get used to
it.
In my opinion, that is why the start-at-one variable is a bad
idea and should be eliminated.

I'm with Kyle on this. But then I'm a hacker and my brain is wired up to
start at 0 rather than 1.

What's the difference between a rookie programmer and an experienced
one?
A novice thinks that a megabyte is 1000 bytes;
An expert thinks that a kilometer is 1024 meters.

Exactly.
Let the novice have the default.
Make it possible for the expert to change it.
The more complex the way to accomplish the change, the happier the expert will be :) :)
