Convert diff-hl tweaks to use-package

Puzzled by this problem I have with :hook.  "(use-package) Hooks"
suggests that if package X defines function X-foo to be used by
package Y in Y-bar-hook, then the idiomatic thing to do is…

  (use-package X
    :hook ((Y-bar . X-foo)))

… but empirically, if Y.el contains…

  (defcustom Y-bar-hook '(Y-quux Y-corge))
  (add-hook 'Y-bar-hook #'Y-grault)

… then Y-bar-hook will be set to '(X-foo Y-grault): it will be missing
the functions added in the defcustom form.

Since add-hook does this:

  (or (boundp hook) (set hook nil))

I am assuming that the problem happens when use-package runs X's :hook
additions before Y is loaded.  No idea (a) if I can reproduce from -Q
(b) if this is a SNAFU from setting always-defer (c) if this could be
solved by sprinkling :after or :requires.
