Moving at the same to a passing "env sigma" style rather than passing
"gl". Not that it is strictly necessary, but since we had to move
functions taking only a "sigma" to functions taking also a "env", we
eventually adopted the "env sigma" style. (The "gl" style would have
been as good.)
This answers wish #4717.

These work on precomputed build logs (in this case, from a recent
partial build of fiat-crypto).
They are meant to serve as human-readable sanity checks of output
format.
Separate out the sane bits of template/init.sh from the ones messing
with directory structure (which are fragile and make assumptions about
where the calling script is sourcing it from).
N.B. The test-suite removes all *.log files, so we use *.log.in.
N.B. We set COQLIB in precomputed-time-tests/run.sh, not the Makefile,
because coqc, on Windows, doesn't handle cygwin paths passed via
-coqlib, and `pwd` gives cygwin paths.
N.B. We have .gitattributes to satisfy the linter (as per
https://github.com/coq/coq/pull/6149#issuecomment-346410990)

The universes of the obligations should all be non-algebraic as they
might appear in instances of other obligations and instances only take
non-algebraic universes as arguments.

This addresses a limitation found in math-comp seq.v file. See the example in
test suite file success/Notations2.v.
To go further and accept recursive notations with a separator made of
several tokens, and assuming camlp5 unchanged, one would need to
declare an auxiliary entry for this sequence of tokens and use it as
an "atomic" (non-terminal) separator. See PR #6167 for details.

When an evar is undefined we need to substitute inside the evar instance.
With help from @herbelin and @psteckler to identify the issue from a
large test case.

We improve one step further the heuristics to sort out if a variable
is a notation variable or a named variable.
This allows to support the following which was still failing.
Reserved Notation "# x" (at level 0).
Inductive I {A:Type} := C : # 0 -> I where "# I" := (I = I).
We rely here on the property that a binding variable of same name as a
notation variables is itself considered bound by the notation.
This becomes however to be a bit tricky for sorting out if the
variable has to be output to the glob file or not.

The file links.v is using utf-8 characters so this is needed at least
to test this file. For the other files, it is not completely without
effect since it makes that symbols like => and forall are respectively
displayed ⇒ and ∀.
Maybe tests with iso-8859-1 or test without a charset option should be
kept.

This file can be used to get in an environment ready to compile Coq
(with `nix-shell`) or to compile and install Coq (with `nix-build`).

PR #1120 was still buggy for the following reasons: variables in the
lhs of the notation were linked in the glob file while they have
nowhere to link to (the binder is the notation string) [I thought the
change I commited in links.html.out was actually improving but it was
an overlook, sorry.]

The two lines that this commit remove are spurious as a `git clean -dfx || true`
is already performed in `test-suite/coq-makefile/template/init.sh`.
While this resolves the accidental dependency on git, I am still unhappy with
this call of `git clean -dfx`.

We refine the criterion for selecting a projection. Before PR#924 it
was alphabetic (i.e. morally "random" up to alpha-conversion). After
PR#924 it was chronological.
We refine a bit more by giving priority to simple projections when
they exist over projections which include an evar instantiation (and
which may actually be ill-typed).

This concerns pr_value and message_of_value.
This has a few consequences. For instance, no more ad hoc message "a
term" or "a tactic", when not enough information is available for
printing, one gets a generic message "a value of type foobar".
But we also have more printers, satisfying e.g. request #5786.

We fix by interpreting the pattern in "change pat with term" in strict
mode by using the same interning code as for "match goal" (even if the
pattern is dropped afterwards).

In particular, using injection and discriminate with option "Keep

Equality".
This fixes bug #5281.
