Options that are specific to a single key definition are not supported (e.g. "sort -k 2,3n -k 4,4"). Should you try to specify such definitions, sort will return with EXIT_FAILURE and an error message. Instead, all key definitions exclusively use the global settings. It always behaves like -b was set.
