one more issue here... we should set argzero ($0) at this point if cmd is
set since we won't execute the code for *runscript non-NULL.  This affects

zsh -c 'echo $0' foo

where time-honoured (well, time-somethinged anyway) behaviour is that $0
returns "foo".  I'll add a test for this, too.

I don't think it's right to set scriptfilename in this case (i.e. -c,
obviously we set it if there's a real script), however.  It's used for
debugging and it's just confusing to have the debug output look like it's
running a script it isn't.
