Should the tests put a newline after the literal "EOF" token instead
of just ending the file there? Does fresh_perl_is take care of that?
Also, does the empty delimiter still work when there's nothing else
printable on the line, like so? Or with an explicitly empty delimiter
? Because that's occasionally useful.
