Its a step in the right direction.
It seems I have to set :cache yes on every block I use before I invoke
it. My attempt to use a buffer-wide PROPERTY setting for cache did not
pan out.
With org-confirm-babel-evaluate set to t, it prompts for confirmation of
each and every block/call it encounters, which is a bit tiresome. I can
set this to nil, but the potential for causing mischief by
unintenionally evaluating blocks whose results were OK and needed for a
quick report worries me.
Its pretty clear that the machinery needed to capture results is all
there. If I can find time, I'll trace thru what is going on when cache
yes is set and see if I can do so more directly.
