I wil start trying.

I'm afraid I don't understand. 
AFAICS your proposed change produces CEILING or CEILING_ODF in the file, 
depending on the number of arguments used. All other users than version 4.3 and 
up will not know CEILING_ODF.
My suggestion is identical as far as the file is concerned, only I think one UI 
function would be needed (CEILING) as other users than version 4.3 and up will 
not know CEILING_ODF anyway.

This is what I understand from your proposal:
UI      ->      FILE
CEILING CEILING
CEILING_ODF     CEILING or CEILING_ODF

FILE    ->      UI
CEILING CEILING
CEILING_ODF     CEILING_ODF or unknown

This is my suggestion:
UI      ->      FILE
CEILING CEILING or CEILING_ODF

FILE    ->      UI
CEILING CEILING
CEILING_ODF     CEILING or unknown

I'm not afraid of the wiki, I know my flaws (as you do, by now) and I don't 
want to burden the whole world with it ;-)

Great. I applicable I will update it when the time comes.
