Is this supposed to be a comment or only the beginning of one?

    #| ; |#

The lexical production rules say this "|#" is ignored as part of a
nested single-line comment, but the implementation regards it as the
end of a multi-line comment.

What about this?

    #|
     "This string |# is unbalanced."
    |#

My intuition tells me the quoted "|#" does not terminate the comment,
but the SRFI and implementation say that it does.  Should it be
possible to comment out strings and single-line comments that contain
the comment delimiters?
