We use this approach for reading of a client input on a remote server:
see client_read() in src/box/lua/console.lua ('\r' here to handle telnet
connections, see fa1aa01e49f323557fc981f7a76d85f99a9c7990).

Those delimiter was introduced before implementing local_check_lua(),
which works on a client side (both for local console and a client for a
remote console): when a delimiter is not set, we read input line by line
and try to parse it as a Lua statement using loadstring().

There are some flaws however:
https://github.com/tarantool/tarantool/issues/4082

I suspect the latter approach is not usable for cases where we have no
Lua interpreter on a client side (say, for test-run); I mentioned it to
provide more broad information.
