app --version should not invoke default_command #206

Dave,

I have an app with default command set to open up a shell from which other commands can be typed.

It's working fine, except that if I invoke 'app --version', I would expect the app to /not/ invoke the default command and simply report the version. 'app --help' works like this, just printing the help text without bringing up the shell afterwards. Seems 'app --version' should work the same way.

I guess I didn't consider having a default command for the root level. Much of GLI assumes that you want a UI where the user specifies a command to run. Still, the behavior as it stands seems surprising.

Thanks, Dave. The pattern is like the ri command in ruby, or lvm, or mdadm. No args, and you go into a shell. I think its a useful default command. My app is an accounting app that has noticeable start up delay that is best avoided when you intend to issue several commands.
