parse_long_opt always matches both --opt and --no-opt for any option "opt", and only get_value checks whether --no-opt is actually valid. Since the options for git branch contains both "no-merged" and "merged" there are two matches for --no-merge, but no exact match. With this patch the negation of a NONEG option is rejected earlier, but it changes the error message from "option `no-opt' isn't available" to "unknown option `no-opt'".
