#150 Xelatex quits with "Emergency stop" when \end{document} is missing

[Anonymous]

If \end{document} is missing, Xelatex quits with an emergency stop, rather than displaying a related error message.

Isn't that the expected behavior if you're running it in \nonstopmode? Which may be the default mode if it's being run from some kind of front-end/shell/editor.
