I see, thanks.  Since I'm new to this, can I confirm my understanding 
here?  It tests whether the 'org-export-current-backend' variable is
set, which means we're currently exporting, and if so, we set the 
:eval argument to "never".  Otherwise we set it to "yes", which means
evaluate it without asking.

Assuming that understanding is correct, I have a couple of followup

1) http://orgmode.org/manual/eval.html doesn't list the "yes" option, 

2) Is there a similar variable I might test to check whether it's currently
doing an explicit C-c C-c action?  If there were, I might prefer 
something like :eval (if org-export-current-backend "never" (if 
org-doing-c-c-c-c "yes" "query")), so that I cover some other
scenario besides export or C-c C-c.

3) Finally, is there a way to add this argument fanciness implicitly
to *all* the source blocks in my file?  Or will it have to go on 
all of them?

Thanks much.
