This might actually be a good solution for the shell block you mention
below.

As an interim solution you could add a :results scalar header argument
to your sh code block, then pass the output of that code block to a
parsing code block (namely the one from my previous email).  That's
certainly not idea, but it should work for the moment.

Alternately if ledger supports a more clearly delimited output format
(e.g. csv) then that would probably work as well.

This would probably be a good addition to ob-sh (and any other language
which doesn't have a defined list syntax).  I'll add this idea to the
babel dev stack, but I'm swamped for the next week or so.
