Good news (at least from my selfish point of view) is that my recent  
changes had nothing to do with this issue.  Looks like this has been  
broken for 10 (!) years.  Goes to show you either 1) how little anyone  
uses the PHP filter feature (probably true) or 2) how rare this kind  
of mixed line-ending is in real data.
