"mixed" means created like win95, but support to read winnt field. So,
it is compatible to win95. And even if user is using winnt option, the
file created can be readed on win95, win95 will ignore the lcase field,
and just display filename as upper case though.

I.e. created filename by any options can read on any plathome, it may
ignore the lcase field though. And, even if user is using "winnt", many
plathome wouldn't be supporting it.

Well, I think changing default by fstype is confusable.
