It looks like I underestimated the scope of the problem.  It looks like
none of the previous value fields (MLST, ALST, LALM, OVAL, ORBV, ...)
get initialized for any recordtype.  Given how uniform this appears I
have to ask: is this a feature?  I think the answer should be no.

I encountered this problem using streamdevice with a serial device
(sr725).  It has non-volatile memory for settings, so I want my output
records to initially read the current value.  The obvious way to was to
use '@init' which happens before the record is processed (I think).

Unless the current behavior changes the only way this can work is if I
mark all settings PINI=YES and hope there are no side effects to
re-setting a parameter.

This seems like an obvious problem, so I can't help but think that I
must be missing something here...
