I can answer my own question:
http://mywiki.wooledge.org/NullGlob
"nullglob is not on by default because there are other cases where its
behavior would be extremely disconcerting. For example, ls behaves
quite unexpectedly if an unmatched glob is removed from the argument
list:"

I actually found some occurrences in the aif codebase where I enable
nullglob, probably the right way forward is to disable those again after
the "critical codepath", check if i didn't break anything else, and then
merge your patch.
