[O] Changing [X] by something else

[François Pinard]

Hi, Org people.

I notice in org.el that [X] is hard-wired, while I would have liked the
possibility of changing it by [✓] in my things, which I find both softer
and cleaner.  Could these ([ ], [-] and [X]) be turned into variables?
The difficulty might be to recognize them properly, I guess.

While it would be nice that I could change it, it might also have a
negative effect, making Org files less interoperable between people.  On
the other hand, the TODO keywords are already changeable, so there is a
kind of precedent :-).

Just a thought.

François
