Good point. In fact my statement below is wrong:

As you say 'ls' just alerts you to the fact that the directory 
doesn't exist it is still not an "error" in a programming sense.

I guess the only real error ls returns will be cases where it
gets confused about the state of a directory or something. Come 
to think of it I'm not sure I've ever seen 'ls' return an actual 
error message (eg. with the word 'error' in it...) and playing 
with it I can't find a way to force it to either...
