Commits from fac8367 and onward break Docker volume mounting.

When mounting using sudo x11docker --network=host -i -g --share=ros --env TERM=screen-256color --hostdisplay --sudouser --verbose <container> I now get this error message from commit fac8367 and onward:

x11docker ERROR: Unknown option ros
  Parsed options:
   --network 'host' -i -g --share 'ros' --env 'TERM=screen-256color' --hostdisplay --sudouser '' --verbose '' -- '<container>'

  Type 'x11docker --help' for usage information
  Debug options: '--verbose' (full log) or '--debug' (log excerpt).
  Logfile will be: 
  Please report issues at https://github.com/mviereck/x11docker

Commits before that work as expected and mount the ros volume at /ros.

Thank you for the report!
I've fixed the issue, the fix is in latest master. I'll publish a new release soon.

Thanks for the quick response!
The newest version 7.1.2 gives me the same error, unfortunately.

Ups, yet another bug.
I've fixed one first that removed the volume support.
But in your case it was a parsing error in the first place: option --gpu takes an optional argument, but -g (should) not. Is fixed now.

Great stuff, now it works!
