Subject: Continuing r12485-12486 (cleaning around name generation) - backtrack
 on incompatibility introduced in intro while trying to   simplify the
 condition about when to restart the subscript of a name   (the legacy says:
 find a new name from x0 if the name xN exists in   the context but find a new
 name from xN+1 if the name xN does not   exists in the context but is a
 global to avoid). - made the names chosen by "intro" compliant with the ones
 printed in   the goal and used for "intros until" (possible source of rare  
 incompatibilities) [replaced the use of visibly_occur_id for   printing the
 goal into a call to next_name_away_in_goal] - also made the names internal to
 T in "T -> U" printed the same in   the goal as they are while printing T
 after it is introducted in the   hypotheses [non contravariant propagation of
 boolean isgoal in   detype_binder] - simplified a bit visibly_occur_id (the
 Rel and Var cases were useless as   soon as the avoid list contained the
 current env); still this function is   costly with polynomial time in the
 depth of binders - see file output/Naming.v for examples
