Subject: Allows recursive patterns for binders to be associative on the left.

This makes treatment of recursive binders closer to the one of
recursive terms. It is unclear whether there are interesting notations
liable to use this, but this shall make easier mixing recursive
binders and recursive terms as in next commits.

Example of (artificial) notation that this commit supports:

  Notation "! x .. y # A #" :=
    (.. (A,(forall x, True)) ..,(forall y, True))
    (at level 200, x binder).
