Regression displaying help

[nandoconde]

Hello.

I've noticed that Debugger help no longer prints correctly \\ linebreaks in debugging REPL help command ?.

I think this started happening after the regression #284 and its fix.

Thanks for everything!

I'm pretty sure it is a regression in Julias Markdown rendering. Not much that can be done about it from here :/
