Subject: [PATCH] * (bug 275) Section duplication fix Clear the section and
 prepare merged-section full text for the edit form before save, so that late
 conflicts don't create a bogus form. Problems were: - duplication of entire
 page into the section on final save - conflict form showed bogus diff
