Replying to my own question here, but I'd appreciate some input from 
someone who understands the intricacies of the MARC<->Koha links.

I've looked at the relevant templates (NPL, English) and it seems that 
something is displayed in the "Call Number" column only if 
biblioitems.classification is set.  This is linked (by default) to 942j 
("Location (call number prefix code)").  If that's set it displays 
biblioitems.classification, just the call number prefix, not the whole 
call number.  There's another template variable called "class" that 
seems more like what should be checked and displayed: concatenation of 
biblioitems.classification, Dewey and biblioitems.subclass.

Koha seems to be a bit inconsistent in the handling of call numbers, it 
seems that much of the time the whole call number (in our case Dewey 
Decimal Code) is stored in the k subfield but in others it's made up of 
pieces stored in j, k and l subfields.

Is there any way to get the call number displaying properly without 
having to edit the templates?  I'm not keen on template editing, it's 
just one more thing we have to review and upgrade for each new version 
of Koha.
