Don't be alarmed if the pull request process takes some time. It can take a few days to get feedback, approval on the final changes, and then a merge. Coq doesn't release new versions very frequently so it can take a few months for your change to land in a released version. That said, you can start using the latest Coq `master` branch to take advantage of all the new features, improvements, and fixes.
+Whitespace discipline (do not indent using tabs, no trailing spaces, text files end with newlines) is checked by Travis (using `git diff --check`). We ship a [`dev/tools/pre-commit`](/dev/tools/pre-commit) git hook which fixes these errors at commit time. `configure` automatically sets you up to use it, unless you already have a hook at `.git/hooks/pre-commit`.
+
Here are a few tags Coq developers may add to your PR and what they mean. In general feedback and requests for you as the pull request author will be in the comments and tags are only used to organize pull requests.

See the [GitHub documentation](https://help.github.com/articles/about-git-rebase/) for a brief introduction to using `git rebase`.

-\subsection{Notations and simple binders}
+\subsection{Notations and binders}
+
+Notations can include binders. This section lists
+different ways to deal with binders. For further examples, see also
+Section~\ref{RecursiveNotationsWithBinders}.
-Notations can be defined for binders as in the example:
+\subsubsection{Binders bound in the notation and parsed as identifiers}
+
+Here is the basic example of a notation using a binder:
+
+\begin{coq_example*}
+Notation "'sigma' x : A , B" := (sigT (fun x : A => B))
+ (at level 200, x ident, A at level 200, right associativity).
+\end{coq_example*}
+
+The binding variables in the right-hand side that occur as a parameter
+of the notation (here {\tt x}) dynamically bind all the occurrences
+in their respective binding scope after instantiation of the
+parameters of the notation. This means that the term bound to {\tt B} can
+refer to the variable name bound to {\tt x} as shown in the following
+application of the notation:
+
+\begin{coq_example}
+Check sigma z : nat, z = 0.
+\end{coq_example}
+
+Notice the modifier {\tt x ident} in the declaration of the
+notation. It tells to parse {\tt x} as a single identifier.
+
+\subsubsection{Binders bound in the notation and parsed as patterns}
+
+In the same way as patterns can be used as binders, as in {\tt fun
+ '(x,y) => x+y} or {\tt fun '(existT \_ x \_) => x}, notations can be
+defined so that any pattern (in the sense of the entry {\pattern} of
+Figure~\ref{term-syntax-aux}) can be used in place of the
+binder. Here is an example:
+
+\begin{coq_eval}
+Reset Initial.
+\end{coq_eval}
+
+\begin{coq_example*}
+Notation "'subset' ' p , P " := (sig (fun p => P))
+ (at level 200, p pattern, format "'subset' ' p , P").
+\end{coq_example*}
+
+\begin{coq_example}
+Check subset '(x,y), x+y=0.
+\end{coq_example}
+
+The modifier {\tt p pattern} in the declaration of the notation
+tells to parse $p$ as a pattern. Note that a single
+variable is both an identifier and a pattern, so, e.g., the following
+also works:
+
+% Note: we rely on the notation of the standard library which does not
+% print the expected output, so we hide the output.
+\begin{coq_example}
+Check subset 'x, x=0.
+\end{coq_example}
+
+If one wants to prevent such a notation to be used for printing when the
+pattern is reduced to a single identifier, one has to use instead
+the modifier {\tt p strict pattern}. For parsing, however, a {\tt
+ strict pattern} will continue to include the case of a
+variable. Here is an example showing the difference:
+
+\begin{coq_example*}
+Notation "'subset_bis' ' p , P" := (sig (fun p => P))
+ (at level 200, p strict pattern).
+Notation "'subset_bis' p , P " := (sig (fun p => P))
+ (at level 200, p ident).
+\end{coq_example*}
+
+\begin{coq_example}
+Check subset_bis 'x, x=0.
+\end{coq_example}
+
+The default level for a {\tt pattern} is 0. One can use a different level by
+using {\tt pattern at level} $n$ where the scale is the same as the one for
+terms (Figure~\ref{init-notations}).
+
+\subsubsection{Binders bound in the notation and parsed as terms}
+
+Sometimes, for the sake of factorization of rules, a binder has to be
+parsed as a term. This is typically the case for a notation such as
+the following:
\begin{coq_eval}
Set Printing Depth 50.
@@ -510,18 +617,53 @@ Set Printing Depth 50.

+Notation "{ x : A | P }" := (sig (fun x : A => P))
+ (at level 0, x at level 99 as ident).
+\end{coq_example*}
+
+This is so because the grammar also contains rules starting with
+{\tt \{} and followed by a term, such as the rule for the notation
+ {\tt \{ A \} + \{ B \}} for the constant {\tt
+ sumbool}~(see Section~\ref{sumbool}).
+
+Then, in the rule, {\tt x ident} is replaced by {\tt x at level 99 as
+ ident} meaning that {\tt x} is parsed as a term at level 99 (as done
+in the notation for {\tt sumbool}), but that this term has actually to
+be an identifier.
+
+The notation {\tt \{ x | P \}} is already defined in the standard
+library with the {\tt as ident} modifier. We cannot redefine it but
+one can define an alternative notation, say {\tt \{ p such that P }\},
+using instead {\tt as pattern}.
+
+% Note, this conflicts with the default rule in the standard library, so

+\end{coq_example}
+
+To enforce that the pattern should not be used for printing when it
+is just an identifier, one could have said {\tt p at level
+ 99 as strict pattern}.
+
+Note also that in the absence of a {\tt as ident}, {\tt as strict
+ pattern} or {\tt as pattern} modifiers, the default is to consider
+subexpressions occurring in binding position and parsed as terms to be
+{\tt as ident}.
