Problem
The same description is used in the compact listing of subcommands, as in the full help for a subcommand. In the former case a one-liner makes sense, but may want multiple lines in the full command description.

A work-around is to add a long description after the built-in help in
.addHelpText('after', longDescription).Solution
Add optional
.summary().For backwards compatibility, the description is used for the subcommand listing if the summary is missing. So by default there is no change in existing programs.
ChangeLog
.summary()for a short summary to use instead of description when listing subcommands in help
