ah, but that's not globbing, that is improper escaping. So, IMHO,
those scripts are broken (and yes, a space would tickle the
bug). Scripts should always be prepared for funny characters in
filenames; in this case it would be
for file in "`ls | grep Ubu`"; do echo "$file"; done
so... ok, if you think what should be fixed are filenames and not the
tools, that's your POV and I respect it, but please don't call it
"globbing". Call it "interpolation" or "substitution" if you need
something word-size.
