  ;;; Whitespace
  (defun crafted-writing-configure-whitespace (use-tabs &optional use-globally &rest enabled-modes)
    "Helper function to configure `whitespace' mode.

  Enable using TAB characters if USE-TABS is non-nil.  If
  USE-GLOBALLY is non-nil, turn on `global-whitespace-mode'.  If
  ENABLED-MODES is non-nil, it will be a list of modes to activate
  whitespace mode using hooks.  The hooks will be the name of the
  mode in the list with `-hook' appended.  If USE-GLOBALLY is
  non-nil, ENABLED-MODES is ignored.

  Configuring whitespace mode is not buffer local.  So calling this
  function twice with different settings will not do what you
  think.  For example, if you wanted to use spaces instead of tabs
  globally except for in Makefiles, doing the following won't work:

  ;; turns on global-whitespace-mode to use spaces instead of tabs
  (crafted-writing-configure-whitespace nil t)

  ;; overwrites the above to turn to use tabs instead of spaces,
  ;; does not turn off global-whitespace-mode, adds a hook to
  ;; makefile-mode-hook
  (crafted-writing-configure-whitespace t nil 'makefile-mode)

  Instead, use a configuration like this:
  ;; turns on global-whitespace-mode to use spaces instead of tabs
  (crafted-writing-configure-whitespace nil t)

  ;; turn on the buffer-local mode for using tabs instead of spaces.
  (add-hook 'makefile-mode-hook #'indent-tabs-mode)

  For more information on `indent-tabs-mode', See the info
  node `(emacs)Just Spaces'

  Example usage:

  ;; Configuring whitespace mode does not turn on whitespace mode
  ;; since we don't know which modes to turn it on for.
  ;; You will need to do that in your configuration by adding
  ;; whitespace mode to the appropriate mode hooks.
  (crafted-writing-configure-whitespace nil)

  ;; Configure whitespace mode, but turn it on globally.
