This is the definition:
 
(defcustom completions-format nil
  "Define the appearance and sorting of completions.
If the value is `vertical', display completions sorted vertically
in columns in the *Completions* buffer.
If the value is `horizontal' or nil, display completions sorted
horizontally in alphabetical order, rather than down the screen."
  :type '(choice (const nil) (const horizontal) (const vertical))
  :group 'minibuffer
  :version "23.2")
 
There is no reason for the `nil' choice.  Please remove it and make the
default value `horizontal'.  Occam's razor (KISS) and clarity for users
argue for this.
