Sakthipriyan Vairamani afd7e37ee0 repl: better empty line handling ...

In REPL, if we try to evaluate an empty line, we get `undefined`.

    > process.version
    'v2.3.4'
    >
    undefined
    >
    undefined
    >

This patch prevents `undefined` from printing if the string is empty.

    > process.version
    'v2.3.5-pre'
    >
