Help should group commands with aliases

[kidomine]

I noticed that in 2.1.0-RC1, shell methods with multiple keys are presented differently when help is invoked.
For example:

@ShellMethod(key={"key1", "key2"}, value = "Command that does something")
public String doSomething()
{
    // do something
}

Below is the comparison of output when typing help:

2.1.0-M5 (and earlier)	2.1.0-RC1
Sample Commands key1, key2: Command that does something	Sample Commands key1: Command that does something key2: Command that does something

In 2.1.0-RC1, the command description is repeated for each key. This makes the help output look cluttered. This can quickly get confusing if the developer intentionally had commands that have similar descriptions.

Is this new behavior intentional?
Is it possible to bring back the behavior similar to that of 2.1.0-M5 and earlier?

Thanks for pointing this out as I think it's an oversight when help content got changed from hardcoded output into templated output(which user could change).

While it probably wasn't obvious this highly relates to #426 meaning these two should go together.

CommandCatalog is currently registered with aliases with a same registration mostly to make things faster. It's probably better to tweak representation model i.e. GroupsInfoModel and its childs not to have alias registrations and then add info about aliases itself as that info is already present in a CommandRegistration. Then templates can make their own choice how to render output.
