In magit, it looks like that if I want to have a diff that highlight changing words, I can either press
D t when I'm in the diff, or put in my .emacs
(custom-set-variables '(magit-diff-refine-hunk all))
However, it turns out that the changing words are highlighted only if I move the buffer cursor near to the line that changed. So for example if I have two changes in the file, then I need to move my cursor to the diff of the second part of the file to see the changes.
Can I set it up so that the refine diff is displayed across all the buffer ?
