Move the code for handling a full match of long_name first and get rid of negations. Reduce the indent of the code for matching abbreviations and remove unnecessary curly braces. Combine the checks for whether negation is allowed and whether arg is "n", "no" or "no-" because they belong together and avoid a continue statement. The result is shorter, more readable code.
