You have forgotten the cases where glob() does not come into the
picture, which is what I'm talking about. Also, glob() can return
unsorted results if the caller requests it.
Here's an example with and without globbing:

$ rm -i * # this works, since glob() usually returns a sorted list
remove 0000AAAA? ^C
$ rm -ri ../test # glob() not used, files are removed in different order
remove ../test? y
remove ../test/g? ^C
