* getopt_long(3): fix case of malformed long optKyle Evans2019-01-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | When presented with an arg string like '-l-', getopt_long will successfully parse out the 'l' short option, then proceed to match '--' against the first longopts entry as it later does a strncmp with len=0. This latter bit is arguably another bug in itself, but presumably not a practical issue as all callers of parse_long_options are already doing the right thing (except this one pointed out). An opt string like '-l-' should be considered malformed and throw a bad argument rather than behaving as if '--' were passed. It cannot possibly do what the invoker expects, and it's probably the result of a typo (ls -l- a) rather than any intent.
