Library C++ conformance question

In this area we have got another consistency issue between the facets 
(num, money, time), which we discussed briefly time ago, Nathan also 
participating: whether eventually eofbit and/or failbit are *assigned* 
vs *OR-ed* to err. AFAICS, if we carefully compare the blanket in 22.2 
and the individual facets, it's a big mess.

I seem to remember that Nathan strongly favor OR everywhere, both for 
eofbit and failbit (and we are currently implementing that behavior).

Paolo.
