When `diff-font-lock-prettify' is `t', outline headers aren't displayed
at the beginning of a line.

The following screenshot displays a
*vc-diff* buffer with outline minor mode enabled and body hidden with
and without `diff-font-lock-prettify' being `t':

Recipe to reproduce:

1. Set `diff-font-lock-prettify' to `t' and enable `outline-minor-mode'
in `diff-mode'; For example:

(add-hook 'diff-mode-hook
	  (lambda ()
            (setq diff-font-lock-prettify t)
	    (outline-minor-mode)))

2. In a *vc-change-log* buffer for emacs sources, find the commit with
hash a8de88e330. Press = (`log-view').

3. Press C-c @ C-t (`outline-hide-body') while in the *vc-diff*
buffer. Observe that outline headers are splitted in multiple lines.
