Not really, but I'd hesitate to remove this, see below.

Try "C-x 4 a" in a function with such a doc string, but without the
escape, and you will see confusion.

I don't think we should remove the escapes in column zero, at least
not yet.  The changes which made them not 100% required are too young,
and I expect many people to edit new sources with old Emacsen (I do
that all the time).

Thanks.
