Subject: git-debrebase: Implement --help, providing a summary.

Provide a usage message.

I'm not convinced an option summary here is a good idea, mainly there
aren't any really important options.  (-f will be advertised when it
is relevant.)  So I have just summarised the most important operations.

Closes:#904990.
