} I'm having a hard time coming up with a combination of options and
} arguments that does this.

Starting from "zsh -f":

zagzig% setopt cshnullglob
zagzig% echo $1+=($2)
zsh: no match
zagzig% $1+=($2)
zagzig% 

The problem of course is that cshnullglob is supposed to be like nomatch
if *nothing* matches -- it's only supposed to be like nullglob if at
least one of several patterns matches.

} But didn't you say the problem was with NULLGLOB?

I originally [in the -users thread] mentioned that the error message
vanishes with either nullglob or cshnullglob.  After I figured out that
it happens because the test string I was using was somehow a valid glob
qualifier -- that is, "(2)" is a valid qualifier, though I have no idea
what meaning it can possibly have -- then I said [on -workers] that it
was limited to cshnullglob.
