Yeah, I pasted the wrong diff into the file I then attached.  Sorry about that.

In the meantime I've made some improvements, including correcting this:

>      _zarun: can't change option: zle

It should now preserve option settings as much as possible.  However,
the function itself can't autoload with "sh" emulation in effect; if
you want to use this where zsh is acting as /bin/sh, you need to use:
  emulate zsh -c 'autoload zargs'

Since Ray asked:  Apply this with
 patch -p1 Functions/Misc/zargs < zargs_patch2.txt
