------------------------------
Dammit, it was stuck at the password phase of my submit-patch.py script. Should
be there now :D

> In postModify* hooks like {{postModifyX(..., Descriptor newDesc)}}, there's
> no way of getting the old descriptor which was there before modification
> happened.
> Having both old and new descriptors will make the hooks more useful.
> We felt the need when we wanted to audit certain events but there was no way
> of deducing them by just seeing 'after-state' of modification.
> To keep the method signatures consistent, i have modified both pre and post
> hooks with new arguments which are well named and commented.
