f_equal, revert, specialize in ML, contradict in better Ltac (+doc)
* "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
