Previously, a "forced" command always exited successfully (with the

Browse Source 
exception of the default 'status' command) regardless of whether the
executed command was actually successfull or not. Forced scripts should
always correctly reflect the outcome of the command.

NOTE: exit values are treated as booleans. We don't care what
      the actual exit value was, only whether it was successfull or not.
