OK, I can start working on the new function and plumb it in. I agree that
"org-base-buffer-file-name" would be better. For the case you mentioned
about an Org buffer not yet associated with a file, that seems like a
complication that we can't solve at this level. Do we leave that as a known
issue, or are there straightforward ways to maybe deal with that? It feels
like that may be case-by-case.

Thanks,

Derek
