parsers: fix some signed comparison issues (spotted by Steve Borho)

commands: correct example in add help text

minirst: support line blocks

commands: add verbose example to help text for add

commands: support verbose help

minirst: report pruned container types

minirst: support containers Text can be grouped into generic containers in reStructuredText: .. container:: foo This is text inside a "foo" container. .. container:: bar This is nested inside two containers. The minirst parser now recognizes these containers. The containers are either pruned completely from the output (included all nested blocks) or they are simply un-indented. So if 'foo' and 'bar' containers are kept, the above example will result in: This is text inside a "foo" container. This is nested inside two containers. If only 'foo' containers are kept, we get: This is text inside a "foo" container. No output is made if only 'bar' containers are kept. This feature will come in handy for implementing different levels of help output (e.g., verbose and debug level help texts).
