It's my recollection that the discussion of this on the austin-group list
led to the conclusion that zsh's native behavior in this case is within
the allowed variation in the POSIX spec.  Vincent, if you're reading this, 
do you disagree, and can you point out why?

My personal feeling is that aliases are an interactive convenience that
should never be used in scripts (including "sh -c") in the first place.

Especially considering that now you can do
	emulate sh -c "..."
which is admittedly a little clumsy to use as in
	zsh -c 'emulate sh -c "..."'
but nevertheless is available to get the desired effect.

Will this cover "emulate -c"?

I'm a bit leery of even starting down this road, because it still fails
to make any difference if the alias definition and use are on the same
line (separated with ";" or "&&" etc.).
