Change looks good. For adding a test, check out https://github.com/nodejs/node/blob/master/test/parallel/test-repl.js. |

That's something that should be investigated separately. Any kind of invalid syntax does it, but is has its uses too:
Same also works on the shell:
The question is if it can be determined if a line can never be valid, like As a first step, I'm fine if you just make sure it not gets parsed as a REPL command. |
Because my test case is leaving the REPL in an inconsistent state, the tests that follow my new test fails ...
