I will prepare a new patch according to what has been discussed so far.
Unless Stefan or anybody else objects.

Stefan, Andrea has already hinted on this in his first mail: I'd need to
call `advice--cd*r' outside of its home package.  For the other issue(s)
it might also be useful to have `advice--p' available.  For example, to
detect advices before actually processing them where they shouldn't be
processed and report more meaningful errors.

Should I just use the double-dash functions or should I "export" them
first in nadvice.el?  If yes to "export", how would that be done?  Just
define a single-dash alias and improve docstrings, if required?

Agreed, will do.

Thanks.
