Comment (by mrclay):

 19666.patch adds an onBeforeSetContent handler to TinyMCE that converts
 newlines to BRs inside PREs just before content is added to the editor.
 You can see how this fixes the behavior in
 [http://fiddle.tinymce.com/cAaaab this fiddle]. wp-admin/js/editor.js
 removes these before POSTing or switching editors, so I think this should
 not add side-effects.

 BTW I was able to fix this during switching in editor.js, but this still
 did not cover the case of when the Visual editor is initialized on page
 load. The tinyMCE event handler covers both cases.
