Well, no, but you can have zsh not call "ls" in the first place if the
pattern doesn't match anything.

You're on the right track in a later posting on this thread where you used
a function rather than an alias.  Aliases can't do anything but simple 
text replacements which happen before any of the glob patterns or other
expansions are evaluated.  If you want to base a decision on the result of
an expansion, you must use a function.

In this case, something like

 lspf() {
   files=( **/*(.N) )
   if (( $#files ))
   then
     ls $files
   else 
     print -u2 "Dude, where's my file?"
   fi
 }

Of course, when I try that, I get "argument list too long: ls" but that's 
a different issue.
