Wrap command description in help

Pull Request

Problem

The "full" command description is not being wrapped in the help.

See: #1785

Solution

Add wrapping of full description.

To work nicely with complex multiline descriptions, some subtle changes to the patterns:

• don't block wrapping just because text contains consecutive empty lines (look for pre-indented lines)
• preserve empty lines in description

Being conservative and marked as semver major because changing help may break client unit tests that depend on the exact output, although only a cosmetic change.
