Edit Wiki Index Content and "rnrn"
Newlines become "rnrn" when editing the Wiki index content.
Fresh installation of v4.0.0 Gamma 4.
Previewing edits to the content of the wiki index look fine, but after saving them, all newlines become "rnrn", ruining formatting to say the least.
Does not affect any other page or area contents that I've found.
PHP 5.3.27 in use.
