* Template instantiation stack messages "staggered" -- why?

Hi all,
Something about GCC's instantiation stack messages seems curious to
me: for a given stack layer, the location in the message is not that
of the template instance name that appears in the same message, but
instead the point of instantiation of a template instance named in
the immediately preceding message. (So the shallowest point of
instantiation is always given in a message that reads "instantiated
from here".)
I can't see anything wrong with this approach, but I can't see the
advantage either. (AFAIK, GCC is unique in this respect: there are
other compilers that produce instantiation stacks, but for each of
the ones that I've seen, each stack message contains both a template
instance name and its corresponding POI.)

I realise that ISO 14.6.4.1 defines "point of instantiation" to mean
something different from the meaning I implied above, but I couldn't
think of a correct short descriptor for those locations.
