The revert has been posted twice on this list and you already applied it
to tty-next with commit ID f28c1d0a78a8c6a217ac5362cb719efa169ae2a7
(thanks btw).  I could have made that clearer...

I'm happy to post it again, but I assumed (wrongly?) that you'd prefer
to cherry-pick it from your own branch.  If you really want me to
post a duplicate, please confirm.

I was concerned that posting a duplicate of a patch you already
picked up would risk further confusion...

Cheers
