Usage help should not show space between short option name and parameter

[remkop]

When an option only has a short name, the usage help message shows a space between the option name and the parameter. This does not happen with long option names.

For example:

  -c= <configurationFile>    Sets the check configuration file to use.
  -C, --checker-threads-number=<checkerThreadsNumber>
                             (experimental) The number of Checker threads (must be greater than zero)
  -d, --debug                Print all debug logging of CheckStyle utility
  -e, --exclude=<exclude>    Directory path to exclude from CheckStyle
  -f= <format>               Sets the output format. Valid values: xml, plain. Defaults to plain
