       sfeed_update: leave IFS unchanged for sfeedrc code
       
       IFS affects the word-splitting of unquoted variable expansions, which can cause
       bugs that are very difficult to track down without in-depth shell knowledge.
       
       Example of affected code:
       
               prog ${var:+--opt "$var"}
       
       Diffstat:
         M sfeed_update                        |       3 +--
