Sets whether short options like {@code -x -v -f SomeFile} can be clustered together like {@code -xvfSomeFile}. The default is {@code true}.
<p>The specified setting will be registered with this {@code CommandLine} and the full hierarchy of its
subcommands and nested sub-subcommands <em>at the moment this method is called</em>. Subcommands added
later will have the default setting. To ensure a setting is applied to all
subcommands, call the setter last, after adding subcommands.</p>
@param newValue the new setting
@return this {@code CommandLine} object, to allow method chaining
