I totally disagree with your total disagreement. I use zsh from
emacs, and I need to get things like `grep *.(c|cc)(^@)' to work,
which requires extendedglob to be set somewhere (lots of other shell
calls are similar). The only simple answer (there are plenty of
horribly complex answers --- three personal startup files is quite
enough) is in .zshenv. I don't want or need a portable environment to
make zsh usable, I want *my* environment.
The only external way of making scripts portable is to use the -f
option. Even then somebody has messed about with /etc/zshenv, which
happens but which I loathe. Furthermore, lots of scripts are also
able to work as functions --- zsh was specifically written that way.
There are so many things you can do with zsh that the only safe thing
to do with scripts is make sure you are explicit about which options
are set and which aren't. Then you're stuck with `emulate -R zsh'.
And if you're religiously into portablity, write ksh scripts and stick
[[ -n $ZSH_VERSION ]] && emulate -R ksh
at the top.
Still, I'll add a warning.
