(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This seems to still be the case with advice-add:

(defun bar ()
  (interactive)
  (forward-line 1))

(advice-add 'bar :before (lambda () (forward-line 1)))

leads to:

---
bar is an interactive Lisp function in ‘/tmp/ad.el’.

(bar)

This function has :before advice: No documentation
---

And no links to the advice.

I'm sure this has come up before -- does advice add no pointers (to
load-history, I guess?) that the help system could pick up?

Or has that been considered and rejected before?
