Just look at the patch, it includes an example.

100 (resp -100) should almost never be used, since they basically mean that
noone should ever have the right to come after (resp before), which is
rather presumptuous.

As the NEWS entry mentions, this semantics mimics that already existing
in add-function (and hence advice-add).
