Prefix ParseResult methods with matched if they return only matched options/positionals #342
Description
Currently methods are named
- options
- positionals
- option(char), option(String)
- positional(int)
- hasOption(char), hasOption(String), hasOption(OptionSpec)
- hasPositional(int), hasPositional(PositionalParamSpec)
These should all be prefixed with matched, so matchedOptions, hasMatchedOption etc.
This helps to clarify the semantics of #340 and #341 .
