riched32: Modified tests to show paragraph break inconsistency.

Several carriage returns followed by a line break were being handled as
a single paragraph break, when actually native richedit controls may
count this as several line breaks.

-     - \r at the end of the text is NOT a line break. This differs from riched20,
