for the moment, only one hypothesis name is accepted after clear
dependent (seems to be also the case for generalize dependent).
Btw, added an alternative name "revert dependent" for "generalize
dependent", since this tactics remove hypothesis from the context.
To be documentated later...

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

is true. E.g. "decide (eq_nat_dec n 0) with H" on
H: n=0 |- (if eq_nat_dec n 0 then 1 else 2) = 1
returns
H: n=0 |- 1 = 1 .

and, with a now generic intropattern "[]", also "as []_eqn", "as []_eqn:H"

inductive types was not taken into account).
- Virtually extended tauto to
- support arbitrary-length disjunctions and conjunctions,
- support arbitrary complex forms of disjunctions and
conjunctions when in the contravariant of an implicative hypothesis,
- stick with the purely propositional fragment and not apply reflexivity.
This is virtual in the sense that it is not activated since it breaks
compatibility with the existing tauto.
- Modified the notion of conjunction and unit type used in hipattern in a
way that is closer to the intuitive meaning (forbid dependencies
between parameters in conjunction; forbid indices in unit types).
- Investigated how far "iff" could be turned into a direct inductive
definition; modified tauto.ml4 so that it works with the current and
the alternative definition.
- Fixed a bug in the error message from lookup_eliminator.
- Other minor changes.

automation.
- Permitted to use evars in the intermediate steps of "apply in" (as expected
in the test file apply.v).
- Back on the systematic use of eq_rect (r11697) for implementing
rewriting (some proofs, especially lemma DistOoVv in
Lyon/RulerCompassGeometry/C14_Angle_Droit.v and tactic compute_vcg in
Sophia-Antipolis/Semantics/example2.v are explicitly refering
to the name of the lemmas used for rewriting).
- Fixed at the same time a bug in get_sort_of (predicativity of Set was not
taken into account).

- evarconv: mauvaise idée d'utiliser la conversion sur la tête d'un
terme applicatif au moment de tester f u1 .. un = g v1 .. vn au
premier ordre : on revient sur l'algo tel qu'il était avant le
commit 11187.
- Bug #1887 (format récursif cassé à cause de la vérification des idents).
- Nouveau choix de formattage du message "Tactic Failure".
- Nettoyage vocabulaire "match context" -> "match goal" au passage.

- Correction divers messages d'erreur
- lorsque rien à réécrire dans une hyp,
- lorsqu'une variable ltac n'est pas liée,
- correction anomalie en présence de ?id dans le "as" de induction,
- correction mauvais env dans message d'erreur de unify_0.
- Diverses extensions et améliorations
- "specialize" :
- extension au cas (fun x1 ... xn => H u1 ... un),
- renommage au même endroit.
- "assert" et "pose proof" peuvent réutiliser la même hyp comme "specialize".
- "induction"
- intro des IH toujours au sommet même si induction sur var quantifiée,
- ajout d'un hack pour la reconnaissance de schémas inductifs comme
N_ind_double mais il reste du boulot pour reconnaître (et/ou
réordonner) les composantes d'un schéma dont les hypothèses ne sont pas
dans l'ordre standard,
- vérification de longueur et éventuelle complétion des
intropatterns dans le cas de sous-patterns destructifs dans induction
(par exemple "destruct n as [|[|]]" sur "forall n, n=0" ne mettait pas
le n dans le contexte),
- localisation des erreurs d'intropattern,
- ajout d'un pattern optionnel après "as" pour forcer une égalité et la
nommer (*).
- "apply" accepte plusieurs arguments séparés par des virgules (*).
- Plus de robustesse pour clear en présence d'evars.
- Amélioration affichage TacFun dans Print Ltac.
- Vieux pb espace en trop en tête d'affichage des tactiques EXTEND résolu
(incidemment, ça remodifie une nouvelle fois le test output Fixpoint.v !).
- Fusion VTactic/VFun dans l'espoir.
- Mise en place d'un système de trace de la pile des appels Ltac (tout en
préservant certains aspects de la récursivité terminale - cf bug #468).
- Tactiques primitives
- ajout de "move before" dans les tactiques primitives et ajout des
syntaxes move before et move dependent au niveau utilisateur (*),
- internal_cut peuvent faire du remplacement de nom d'hypothèse existant,
- suppression de Intro_replacing et du code sous-traitant
- Nettoyage
- Suppression cible et fichiers minicoq non portés depuis longtemps.
(*) Extensions de syntaxe qu'il pourrait être opportun de discuter

- Ajout clause "in" à "remember" (et passage du code en ML).
- Ajout clause "in" à "induction"/"destruct" qui, en ce cas, ajoute
aussi une égalité pour se souvenir du terme sur lequel l'induction
ou l'analyse de cas s'applique.
- Ajout "pose t as id" en standard (Matthieu: j'ai enlevé celui de
Programs qui avait la sémantique de "pose proof" tandis que le nouveau
a la même sémantique que "pose (id:=t)").
- Un peu de réorganisation, uniformisation de noms dans Arith, et
ajout EqNat dans Arith.
- Documentation tactiques et notations de tactiques.

* "f_equal" is now a tactic in ML (placed alongside congruence since
it uses it). Normally, it should be completely compatible with the
former Ltac version, except that it doesn't suffer anymore from the
"up to 5 args" earlier limitation.
* "revert" also becomes an ML tactic. This doesn't bring any real
improvement, just some more uniformity with clear and generalize.
* The experimental "narrow" tactic is removed from Tactics.v, and
replaced by an evolution of the old & undocumented "specialize"
ML tactic:
- when specialize is called on an hyp H, the specialization is
now done in place on H. For instance "specialize (H t u v)"
removes the three leading forall of H and intantiates them by
t u and v.
- otherwise specialize still works as before (i.e. as a kind of
generalize).
See the RefMan and test-suite/accept/specialize.v for more infos.
Btw, specialize can still accept an optional number for specifying
how many premises to instantiate. This number should normally
be useless now (some autodetection mecanism added). Hence this
feature is left undocumented. For the happy few still using
specialize in the old manner, beware of the slight incompatibities...
* finally, "contradict" is left as Ltac in Tactics.v, but it has
now a better shape (accepts unfolded nots and/or things in Type),
and also some documentation in the RefMan

of Zdiv
Some details:
- ZAux.v is the only file left in Ints/Z. The few elements that remain in it
are rather specific or compatibility oriented. Others parts and files have
been either deleted when unused or pushed into some place of ZArith.
- Ints/List/ is removed since it was not needed anymore
- Ints/Tactic.v disappear: some of its tactic were unused, some already in
Tactics.v (case_eq, f_equal instead of eq_tac), and the nice contradict
has been added to Tactics.v
- Znumtheory inherits lots of results about Zdivide, rel_prime, prime, Zgcd, ...
- A new file Zpow_facts inherits lots of results about Zpower. Placing them
into Zpower would have been difficult with respect to compatibility
(import of ring)
- A few things added to Zmax, Zabs, Znat, Zsqrt, Zeven, Zorder
- Adequate adaptations to Ints/num/* (mainly renaming of lemmas)
Now, concerning Zdiv, the behavior when dividing by a negative number is now
fully proved. When this was possible, existing lemmas has been extended,
either from strictly positive to non-zero divisor, or even to arbitrary
divisor (especially when playing with Zmod). These extended lemmas are named
with the suffix _full, whereas the original restrictive lemmas are retained
for compatibility. Several lemmas now have shorter proofs (based on unicity
lemmas). Lemmas are now more or less organized by themes (division and order,
division and usual operations, etc). Three possible choices of spec for
divisions on negative numbers are presented: this Zdiv, the ocaml approach
and the remainder-always-positive approach. The ugly behavior of Zopp
with the current choice of Zdiv/Zmod is now fully covered. A embryo of
division "a la Ocaml" is given: Odiv and Omod.

H: forall (n:nat)(b:bool), P n b
then "narrow H with 0 true" will leave H: P 0 true.
The name for this tactic should ideally be "specialize", but this one
already exists (old stuff, same idea but no "in place" modification,
not documented anymore, still used in users contribs).
