Yes, I'm saying about trailing-dot filename case. Any disadvantage to
standard one is unacceptable to workaround.

Those sound like strange. Well, I expect there is no any change to
standard one for IO-MEGA.

And I can't see what is your read-access mean in here. What did this
expect to behave like e.g. following operations,

$ ls
a.. a. a
$ rm -rf *

$ ls
a..
$ touch a.
$ touch a
...

I assumed you want to define "a." and "a" are different name on
"mv a a.", and _totally_.

Thanks.
