In that case we'll have to make the text longer instead of shorter :-( 
How about the following? In 4.1[1], after

    COMMENT tokens do not occur in the grammar (to keep it readable),
    but any number of these tokens may appear anywhere between other
    tokens

add this phrase and note:

    or at the start or end of a style sheet. (Note, however, that
    a comment before @charset[2] disables the @charset.)
