--raid-mode is the full long option name, but the GNU getopt_long
implementation accepts unique abbreviations for long options, so
--ra, --rai, --raid, --raid- etc. are all valid usages.
I think the -mode part is just unnecessary verbosity and could be
dropped without affecting users, as it is never mentioned outside
the code base.
