I'm not quite following how it's an implementation, since I don't see where it 
does anything like "flags |= GLOB_ONLYDIR | GLOB_MARK;". Maybe there's another 
part of the patch you're missing?

The variable "filter" is a boolean and should be of type bool.

That comment and code look over-complicated. Can't you simply copy nonnull 
entries in-place, in a single pass? That way, the filtered order will be the 
same as the original order.
