Yes; the question is, when "the specified shell" is zsh, what does it mean
to emulate it?  After all, zsh is already zsh ... by definition, any option
not specifically intended for emulation of some other shell is already
being emulated "as if zsh," no matter what its setting.

However, this is mostly thinking about things from an interactive-shell
viewpoint, not from a function/script viewpoint.  So how about this:

We already have to use the -L option essentially all the time, and it makes
little sense to use -L in an interactive context.  Why not overload -L with
this semantics, and leave plain "emulate" as it was?
