I did some tests which show that the only place where the 'p-'
switch is necessary is the function mcrarfs_copyout. I also
noticed something unrelated to your patch which must be fixed
IMO. Encrypted archive entries are listed by rar with a '*'
character prepended to their names - as a consequence all further
operations on this files won't succeed since MC passes to extfs
the wrong name.
