check-names settings

[Peter Laws]

I looked at the docs for check-names and it's a little unclear.  Basically, 
I'd like to stop BIND from caring about underbars ("_").  The docs refer to 
RFCs 1123, 952, and 821 (yep, Postel), but none of them seem to allow 
underbars in domain names, but they are surely used a lot.

So which setting will make it stop complaining?  If I set it to "ignore", 
what else would I lose?
