--------------------------------

Come to find out, we do actually have a case where we need to either expand the width or do something else.

There are currently 3 versions of the 'Set domain config file' command. They're just not all next to each other so it slipped under the radar. 

{noformat}
    -c <config>                        Name of the domain configuration file 
                                       to use (default is "domain.xml")

    -c=<config>                        Name of the domain configuration file 
                                       to use (default is "domain.xml")

    --domain-config=<config>           Name of the domain configuration file 
                                       to use (default is "domain.xml")
{noformat}


I figured out a way to handle multiple-lines on the command side of the output and for comparison handled it this way. I'm not sure what standard-practice is for this scenario though. I've never actually seen it anywhere.

{noformat}
    -c <config>, -c=<config>,           Name of the domain configuration file 
         --domain-config=<config>       to use (default is "domain.xml")
{noformat}

Thoughts?

> For command line parameters where there is both a short or a long version of the same option, the short and long version should be comma separated.  This is similar to how many command line tools display help or in man pages.
> Current output:
> {noformat}
