ad-recover-all
ad-recover-all is an interactive compiled Lisp function in `advice.el
'.
(ad-recover-all)
Recover all currently advised functions. Use in emergencies.
To recover a function means to try to find its original (pre-advice)
definition, and delete all advice.
This is more low-level than `ad-unadvise' in that it does not do
deactivation, which might run hooks and get into other trouble.
