body: <p>How can I disable printing subcommand choices, the ones between curly brackets? Using an example at <a href="http://docs.python.org/dev/library/argparse.html#sub-commands" rel="noreferrer">http://docs.python.org/dev/library/argparse.html#sub-commands</a>, the normal output is:</p>
  
  <pre><code>usage:  [-h] {foo,bar} ...
  
  optional arguments:
  -h, --help  show this help message and exit
  
  subcommands:
  {foo,bar}   additional help
  </code></pre>
  
  <p>What I want is to print this:</p>
  
  <pre><code>usage:  [-h] {foo,bar} ...
  
  optional arguments:
  -h, --help  show this help message and exit
  
  subcommands:
  </code></pre>
  
  <p>Removing just the last line.</p>
