Debian has its own dash which is supposed to be a lightweight
alternative to bash and "for checking POSIX compliance of scripts"
(quote from the packages description). I don't happen to know off-hand
whether POSIX says that echo should default to -e, but dash seems to do
that:

$ dash
$ a=3D"hello\nhi"
$ echo $a
hello
hi
