REVISION SUMMARY
  This was broken in c5897d0eabf515a82a62429a726819cb60e255ae <https://phabricator.kde.org/R205:c5897d0eabf515a82a62429a726819cb60e255ae> suggesting

  Testing suggests that this is not the case, especially since
  the printing to the terminal was handled directly by `process`
  in which case it'll never return. I don't really see how the
  printing could be stopped unless `stdout` or `stderr` is overriden,
  which doesn't seem to be the case.
  
  This is the same as how KDE builtin options are currently handled.
  
  Also remove now unused EXIT command.
