Bug#608234: apt: displays usage instructions on syntax errors on stdout and returns with exit code 0

[Michael Prokop <mika@debian.org>]

Package: apt
Version: 0.8.10
Severity: normal


% apt-get --simulate >/dev/null ; echo $?
0

Obviously this is not a valid command line.
I'd expect to get the usage instructions/error message
on stderr and a return code != 0.
