Yeah, that works well enough.  Pushed that way.

I looked around with this:

git grep 'const.*\[.*[^][0-9].*\].*=.*{'

and found one suspicious-looking use of MAX_ACL_KIND which we could
perhaps define in a way equivalent to what we've done here.  We also
have RM_MAX_ID in a couple of arrays but that looks safe because both
the values and the arrays are auto-generated.

don't look likely to actually cause any trouble.

(There are many arrays sized to numerical constants, but there are about
5000 of those and I'm not in a hurry to verify how they are used.)
