Hi, Maxim!

Thanks for the patch!

Please mention the corresponding commit.

Please provide Tarantool branch too. It is convinient to reviewer to
check that CI is OK.

Lua 5.2 test suite has the different test here:

| RUN([[lua "-e_PROMPT='%s'" -i < %s > %s]], prompt, prog, out)
| local t = getoutput()
| assert(string.find(t, prompt .. ".*" .. prompt .. ".*" .. prompt))

Why did you change it?

Why didn't you adjust the next test with multiple returns too?
See the issue's comment for example [1].
