Description:
my_long_options in mysqld.cc contains duplicate entries, for example

  {"ndb-use-exact-count", OPT_NDB_USE_EXACT_COUNT,
   ...
   0, GET_BOOL, OPT_ARG, 1, 0, 0, 0, 0, 0},
  {"ndb_use_exact_count", OPT_NDB_USE_EXACT_COUNT,
   "same as --ndb-use-exact-count.",
   (uchar**) &global_system_variables.ndb_use_exact_count,
   (uchar**) &global_system_variables.ndb_use_exact_count,
   0, GET_BOOL, OPT_ARG, 1, 0, 0, 0, 0, 0},
  {"ndb-use-transactions", OPT_NDB_USE_TRANSACTIONS,
   ...
  {"ndb_use_transactions", OPT_NDB_USE_TRANSACTIONS,
   "same as --ndb-use-transactions.",
   (uchar**) &global_system_variables.ndb_use_transactions,
   (uchar**) &global_system_variables.ndb_use_transactions,
   0, GET_BOOL, OPT_ARG, 1, 0, 0, 0, 0, 0},

Second copies are useless, as my_getopt treats '-' and '_' as equal on comparison.

How to repeat:
.

Suggested fix:
remove duplicates.
To reduce the confusion and for consistency print all option names in --help with dashes, performing the replacement in my_print_help and my_print_variables.
