Well, anywhere you expand an unquoted variable, or command output via `` or $(), and depend on it being split into separate words. I now religiously use this idiom: ifson ; set -- $( foo ) ; ifsoff for x ; do bar $x ; done to act on separate words output from foo. Basically, I am trying to make my sh(1) scripts look like rc(1) scripts, without the rc bugs and missing features. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
