Eric Lilja commented on KARAF-3217:
-----------------------------------

[~jbonofre] I see. It's unclear to me how these wrapped commands will behave, 
so waiting with judging on that. But what happened to --show-hidden, that used 
to work. Has it been removed in later versions of gogo for some reason? Not 
implemented for scr version >= 2 or something like that?
