Unification in HoTT_coq_061.v was looping with previous commit (while
it was failing with Not_found before previous commit). This "fixes"
the loop by expanding local defs in "imitate" rather than keeping them
explicit. The example is otherwise too large for me to be able to
understand where does the loop come from.
