Current behaviour

$> jboss-cli.sh --commands "connect,version"
Duplicate argument '--command'/'--commands'.

Expected behaviour

$> jboss-cli.sh --commands "connect,version"
JBoss Admin Command-line Interface
...

It works, however, when the --command/--commands is omitted completely, as in:

$> jboss-cli.sh "connect,version"

Therefore, the command/commands arguments should probably be removed from help and usage, if this is the correct behaviour.
