Hi, I found a bug when I tried to use line continuation: prompt: >help he\

lp Unknown command 'he lp' I expect the above one should work, but it add one more space to the input.

Not really sure how this should work in a context of "real shell" vs. interactive shell which is interpreted via jline. It's interesting idea though as it's common case when working with shells like bash, etc.
