change in babel argument processing?

Hello all,

Some of my ledger babel calls have stopped working.  I have tracked it
down to a change in how backslashes are treated.  Formerly, I had
"...\n..." which was interpreted correctly but now require to escape the
backslash "...\\n...", as in the attached example.

I'm posting this as much as a heads up for others as anything else.  I
did not see any mention of this in the list or the change log but could
have obviously missed it easily (apologies if so).

Thanks,
eric

This one does:
