`--unmount` option can't be used

[pacoorozco]

Hi,

If you try to use the --unmount option (plus the mount point) you'll get always the same error:

$ encfs ~/Encrypted ~/Plain  
EncFS Password: 
$ encfs --unmount ~/Plain          
Expecting one argument, aborting.

But if you use the -u flag it will perfectly work:

$ encfs -u ~/Plain                 
Filesystem unmounting: /home/paco/Plain

Other data:

$ encfs --version           
encfs version 1.9.5
