What I wrote is the expansion in "info" output.
In dvi/pdf output, it does expand to "See see Section..." (i.e., no
"*Note" there), so I'll have to revise the advice in the comment.
Per "info texinfo",

    8.4 address@hidden'

    The address@hidden' command generates a cross reference for the beginning 
of a
    sentence.

So any preceding token should be punctuation.

Thanks.
