P-wrapper tweak since WTS prefers newlines outside p-tags.

* WTS prefers newline outside p-tags based on how it merges
  separators across nodes.  If "\n " is part of trailing content
  in a p-node, the trailing space eliminates the "\n" from
  consideration as a newline that meets separator constraints.
  However, this is not the case if the "\n " is outside the p-node.

  Ex: "<p>a\n </p>\n<p>b</p>" vs. "<p>a</p>\n \n<p>b</p>"

  WTS serializes the latter html better than the former one where
  it introduces an extra newline between 'a' and 'b'.

* Fixes RTing of "a\n \nb"

* No change in parser test results although there is some
  improvement in output in some failing tests.

* Eliminates all RT errors from en:Johnny%20Harris%20(musician)
