bug#14533: 24.3.50; Documentation for icomplete.el (ido style completions)

[Jambunathan K]

Document following keybindings.

    (defvar icomplete-minibuffer-map
      (let ((map (make-sparse-keymap)))
        (define-key map [?\M-\t] 'minibuffer-force-complete)
        (define-key map [?\C-j]  'minibuffer-force-complete-and-exit)
        (define-key map [?\C-.]  'icomplete-forward-completions)
        (define-key map [?\C-,]  'icomplete-backward-completions)
        map))

revno: 111793 introduces C-. and C-, bindings for both ido and iswitchb
so that all the "incremental completion" libraries share the same
prefix.

Document following user options:

    icomplete-hide-common-prefix
    icomplete-first-match
    icomplete-separator

Explicitly mention the following setting.

        (setq icomplete-with-completion-tables t)

so that one can get incremental completion for bookmarks etc.

    (custom-set-variables
     '(completion-category-overrides
       (quote
        ((buffer
          (styles basic substring))
         (bookmark
          (styles substring))))))
