Allow arbitrary values for [SetWrapperReferenceFrom]

Source/bindings/IDLExtendedAttributes.txt

 #
 # This file describes all Blink IDL extended attributes and allowed values.
 # If any IDL file uses an extended attribute or values not listed below, the
 # build will fail.
 # If you would like to add a new extended attribute or value, please:
 #     (1) add the extended attribute or value to this file
 #     (2) add an explanation to the Blink IDL extended attributes document:
 #         http://www.chromium.org/blink/webidl/blink-idl-extended-attributes
 #     (3) add appropriate test cases to run-bindings-tests
 #
 # The syntax of this file is as follows:
 #     - One extended attribute per one line: Name and (optionally) Values.
 #     - "Attr" means that the Attr does not take a value, i.e. [Attr].
 #     - "Attr=X" means that Attr takes a required value, which must be X;
 #       i.e. [Attr=X].
 #     - "Attr=X|Y|Z" means that Attr takes a required value, and the valid
 #       values are X, Y, and Z, and combinations thereof;
 #       e.g. [Attr=X], [Attr=Y], [Attr=X|Z].
 #       The separator must be | or &, so [Attr=X&Z] is also valid; the
 #       separator makes a difference for Conditional, but otherwise is simply
 #       a style convention.
 #     - "Attr=|X|Y|Z" means that Attr takes an optional value, whose valid
 #       values (if present) are X, Y, and Z, and combinations thereof; e.g.
 #       [Attr], [Attr=X], [Attr=Y], [Attr=X|Z], [Attr=X|Y|Z], [Attr=X&Z].
 #       Note that including an empty value in the list, as in [Attr=X||Y],
 #       is NOT valid: the value is optional, but empty values are not allowed.
 #     - "Attr=*" means that Attr takes a required value, which can be
-#       arbitrary and combinations thereof, e.g. [Attr=IndexedDB],
+#       arbitrary, and combinations thereof, e.g. [Attr=IndexedDB],
 #       [Attr=DeleteFunction], [Attr=X|Y].
 #     - "Attr=|*" means that Attr takes an optional value, which can be
 #       arbitrary, e.g. [Attr], [Attr=X].
 #     - "Attr=X|*" means that Attr takes an required value, which can be
 #       arbitrary, but that "X" is standard, e.g. [Attr=X], [Attr=Foo].
