Corion,
I have wondered this for sometime, but never asked. The docs for glob in recent versions indicate that it is implemented using File::Glob and the documentation indicates that File::Glob is a Perl extension for BSD glob routine. If this is the case, than shouldn't glob already be doing a bsd_glob?

Update: I just read further down in the docs where it says: "Due to historical reasons, CORE::glob() will also split its argument on whitespace, treating it as multiple patterns, whereas bsd_glob() considers them as one pattern."
