Glob returns a value when no match occurs

This sure seems like a bug to me:


    [573] belay:~:> which foo
    foo is a function
    foo ()
    {
        arr=(*.txt);
        echo "address@hidden files found:";
        for x in "address@hidden";
        do
            echo "  $x";
        done
    }
    [574] belay:~:> touch foo.txt bar.txt baz.txt
    [575] belay:~:> foo
    3 files found:
      bar.txt
      baz.txt
      foo.txt
    [576] belay:~:> \rm *.txt
    [577] belay:~:> foo
    1 files found:
      *.txt
    [578] belay:~:>


Looks like the glob "arr=(*.txt)" is actually returning the string
"*.txt" when no match occurs.  Either that or the array definition is
picking up on the string when no match occurs.  In either case, this
is aberrant behavior.  Either let the * glob, or don't, but don't mix
the two. ;)
