I've just pushed a commit that reuses <C> for both -i and --color 
(<C>ase and <C>olor, we can still pretend it's mnemonical), simply 
because there are templates out there with <C> in them, which do not 
include "--color".

If anyone really wants to change it to <O>, be my guest.

I haven't found any. OTOH, it doesn't hurt anyone either. Maybe the 
right change would be to make the code use it, actually. Are there use 
cases for changing the value of null-decide dynamically?

And speaking of needs, what is the use case for "--color" without 
"always"? Instead of special-casing Windows and DOS, why don't we always 
use `always' for coloring?
