The trouble with that "doctrine" is that what is surprising is
subjective and context-dependent both in usage and in time. When
these decisions were made, the largest number of zsh adoptees would
have been more surprised by having empty elements kept than removed.
Mysteriously receiving error messages like
ls: : No such file or directory
would have been the surprising thing. Further, many commands neither
understand nor do anything useful with empty string arguments, and zsh
was intended first to be an interactive command shell and only second
a programming language (just a better one than BSD csh).
