Thanks.  I knew there was something fishy.  I was comparing the
before/after code (which had the extra assignments, and differences in
output) not the performance differences between concat/interpolate.

The upshot is that the practice of successive .= operations to avoid
"costly interpolation overhead" is a *lot* worse than I suspected.  :-)
