I think the problem is not in dired, it's in ls-lisp.el, so will only
show on non-Posix platforms which use ls-lisp as a replacement for (a
possibly missing) `ls'.

I'm guessing that somewhere in this chain of calls, we should have
called regexp-quote on the file name.  Could you please look closer at
the code and see where?
