Subject: [PATCH] [lex.pptoken] Turn non-normative text into a note

The last part of this paragraph is non-normative, so turn it
into a note.  Also, the preceding sentence defining whitespace
characters is mostly unrelated to the precedingd defintion of
preprocessing tokens, so start a new paragraph to more clearly
show the comment assoication.

 As described in \ref{cpp}, in certain
 circumstances during translation phase 4, whitespace (or the absence
 thereof) serves as more than preprocessing token separation. Whitespace
 can appear within a preprocessing token only as part of a header name or
 between the quotation characters in a character literal or
 string literal.
