Andreas Schwab 6bbfd1fa98 parse-opt: ignore negation of OPT_NONEG for ambiguity checks ...

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'".
