Yes, I just noticed.  Thanks for that.

While investigating that, I tried switching on
next-error-follow-minor-mode explicitly:

(add-hook 'diff-mode-hook (function () (next-error-follow-minor-mode t)))

But that failed, and then I tried a function that did (setq foo 42),
and that didn't seem to set foo.  

I suspect diff-mode doesn't call diff-mode-hook.  The documentation
for diff-mode doesn't say it does, but diff-mode-hook does suggest it
gets called.  So something seems wrong.
