 Given the lack of consensus otherwise I think ` <unavl>' is the only way 
to go.  I hope there is consensus about this variant being better than 
`<unavail'.

 AFAIK output from `info registers' is not meant for machine consumption 
and as such does not constitute a protocol.  Therefore we can freely 
change it again anytime if we find a better alternative, as long as it is 
comprehensible to a human.

 Thank you for patience and apologies for the long RTT.
