Bug#636783: GR giving advice to TC on overruling

[Ian Jackson <ijackson@chiark.greenend.org.uk>]

I have concluded that it is not going to be feasible for me to find a
wording for an advisory GR which will achieve my objectives.

I'm therefore dropping it from my personal todo list.  I have removed
it from the TC git repo.  If someone else wants to pick it up, they'd
have my support.

Thanks,
Ian.
