Yes, at least from a kernel point of view.  Your shell does wildcards in
userspace, probably by doing getdents and then comparing with possible
matches.  Since the shell itself is not case-insensitive aware, its
comparison is case-sensitive, and you get these apparent weird
semantics.

Not ideal from a user point of view.  But not a kernel bug.  If it
pushes people away from using case-insensitive directories in their
day-to-day work and leave it to only be used by Windows compatibility
layers, maybe that's a win? :)
