It's a general problem that hindered the development of other features
that might benefit from customizable advice-add (namely set-multi-message).

Only personal preference, it seems the default in master is fine
for most users.

The reason why I think no one might want to customize the rest of the cases
is because I believe that next-error-last-buffer is always non-nil, so
all other cases (i.e. 3, 4, 5, 6) are useless and never used.  Isn't it so?
