Issue Description:

Description of Problem:
Documentation Issue: Lexical Structure - Whitespace and Comments section:
first sentence should add "binary"
Link to Lexical Structure - Whitespace and Comments

Expected to see:
Whitespace has two uses: to separate tokens in the source file and to help determine whether an operator is a prefix, postfix, or a binary (see Operators), but is otherwise ignored.
Actually observed:
Whitespace has two uses: to separate tokens in the source file and to help determine whether an operator is a prefix or postfix (see Operators), but is otherwise ignored.

Evidence:
Link Lexical Structure - Operators
The six paragraph after the "Note" states:
"The whitespace around an operator is used to determine whether an operator is used as a prefix operator, a postfix operator, or a binary operator. This behavior is summarized in the following rules:"

and the first rule states:

if an operator has whitespace around both sides or around neither side, it’s treated as a binary operator. As an example, the +++ operator in a+++b and a +++ b is treated as a binary operator"

A description of the environment that reproduces the problem.
This issue happens is all Swift Documentation.

I therefore submit the first sentence of the Lexical Structure - Whitespace and Comments should add binary.
