[Samba] Reproducible samba bug with directory name

[Greg Freemyer]

Simo,

I just tried to create a directory name ending with a dot from XP.
You're correct, it silently truncates the dot.

And I tried creating a simple test directory "asdf." from Linux on my
filesystem, and only the mangled name is showing up from XP.

Still seems like a bug to me especially since a cifs client shows the
correct name, but if this is "works as expected", I'll just be quiet
about it.
