As I said, it *is* possible for a privileged script to be secure. IMO
it's up to the person writing such scripts to use the methods
available. We shouldn't disable a feature just to make this easier. I
think field splitting should be off by default in zsh, but
SH_WORD_SPLIT or some other option should turn it on. (Maybe
SH_WORD_SPLIT should do field splitting on words, and SH_FIELD_SPLIT
should do the current filed splitting on parameters.)
In any case, this is not a critical issue, and can wait until after 3.0.
