Thanks for the report. The shell is trying to find the end of the command
to figure out how to store it in the history. When you're parsing a here-
document, you need to leave the newlines in the history instead of maybe
adding a semicolon. That code just needs to be more aware of when it can
not parse due to being in the body of a here-document.
