Wrong indentation when mixing single and multiple form parameters

[dadoonet]

Sounds like I've get a wrong indentation when doing this:

@Parameter(names = { "--help"}, help = true, description = "Display help")
private boolean help;

@Parameter(names = { "--verbose", "-v" }, description = "Debug mode")
private boolean debug = false;

Output is:

Usage: river [options] 
  Options:
    --verbose, -v
       Debug mode
       Default: false
        --help
       Display help
       Default: false

When using:

@Parameter(names = { "--help", "-h", "-?"}, help = true, description = "Display help")
private boolean help;

@Parameter(names = { "--verbose", "-v" }, description = "Debug mode")
private boolean debug = false;

Output is this time correct:

Usage: river [options] 
  Options:
    --verbose, -v
       Debug mode
       Default: false
    --help, -h, -?
       Display help
       Default: false

This fixes the indentation:

     return sb.toString();

The ways to work around it are to have more than one option name, or to use a single dash even for long option names.

The commit message for that line reads:

Better usage().

Now sorting correctly and aligning -- options on the same column.
