No way to control it yet; maybe flag use_evars_pattern_unification
should be generalized for that purpose.

flag to forbid rewriting tactics to instantiate an evar of the goal
while looking for subterms (this is not clear that we always want that
for rewrite but we certainly want it for autorewrite; see comments
by Charguéraud on coqdev Oct 2010).
In a few cases in the theories, a pre-existing evar of an hyp used for
rewriting is instantiated by the rewriting step. Let's accept this at
the current time.
We have to make progress towards documenting and stabilizing the
strategy for matching/unifying subterms in rewrite/induction/set...

parameters of inductive types when these variables cannot bind the
conclusion of the inductive type (done for "return" predicates but
still to be done for non strictly positive binding occurrence, as e.g. in
"Set Implicit Arguments. Inductive I A:A->Prop:=C a:(forall A, A)->I a."
which should morally be accepted but is not).

Stop using hnf_constr in unify_type, which might unfold constants

for adding spaces were not taken into account in notations containing
patterns of the form "{ ident symbol", paradoxically resulting in
adding extra spaces, e.g. when printing the type "{ x | P x }" of
"exist", due to interferences with the heuristic for adding breaking
points in Metasyntax.make_hunk).
Also adapted output of test InitSyntax.v after commit r14018 improved
the printing of "ex P" and "sig P".

Note: I'm unsure about some subtyping error case apparently involving
aliases of inductive types (middle of Subtyping.check_inductive); I
bound it to some NotEqualInductiveAliases error, but this has to be
checked.

Before this patch, hints such as "Hint Resolve -> a" in success/Hints.v
were erroneously considered "eauto-only". We try to clarify the big
boolean expression via "if", and for the moment we remove
the detection of "nonlinearity" via duplicated_metas : on the example,
some nonlinearity was found for strange reason (beta expansion ?), and
after some discussion with Hugo, it is unclear whether this nonlinearity
stuff is useful at all. The next coqbench might provide some answer
to this question, we'll see

This variant was ignoring its second argument, and didn't exactly
respect its documented specification. This is fixed by removing the
variant altogether.

We now keep some type information in the "info" field of constructors
and cases, and compact a match with some default branches (or remove
this match completely) only if this transformation is type-preserving.
