• Add support for changing the usage width via the usage_width option on the directive
• Mark document as always needs an update (as the underlying content is coming from outside the sphinx documents)
• Help messages are now interpreted as reStructuredText
• Matching curly braces, single and double quotes in help text will be marked as string literals
• Help messages containing the default(s) word do not show the default value (as often this indicates the default is already documented in the help text)
