Hi,

This patch creates a new operator for sets : /-
It allows to get the nth parent of all the elements of a set.
For example, if user is cn=user,ou=people,dc=example,dc=com :
user/-1 : resolves to set {ou=people,dc=example,dc=com}
user/-2 : resolves to set {dc=example,dc=com}
Of course it works the same for sets of more than 1 element.

It is very useful when ACLs depends on hierarchy.
