change in babel argument processing?

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

It is an unexpected consequence of
500abcd7fbe24abc887300faec2058905a13fa33 in which I lazily use `read' to
parse string values.

I fixed it in maint, could you confirm it?

Thank you.

Yes, works fine now (in master which I assume includes updates to
maint).  Many thanks.

Interestingly, keeping \\n also works so at least I don't have to
immediately undo all the changes I made to my tax files... :-)
