I'm happy for your patch below to be applied, although maybe replace
org-babel-table-truncate-at-newline with org-babel-trim, so that
leading/trailing newlines are still removed. It would be nice to retain
org-babel-table-truncate-at-newline if we could tell which evaluations
were headed for a variable -- although this behavior doesn't seem worth
the addition of a new argument to sbe.
