Still a good thing to have it as a terminator. But the loop I proposed
doesn't even touch it: i < N_INJ_TYPES. I'd leave the NULL array
terminator.

We have to make sure to not be overeager to error out - this'll make
using this facility a bit more cumbersome.

So I think your approach was correct to trim it to MAX_FLAG_OPT_SIZE.
__set_inj() will catch any string mismatches anyway.
