Modified console.cpp to allow pasting code with backslashes.

[clort81]

I'm baffled that others haven't brought up this issue, which may mean I have overlooked or misunderstood something.

I frequently ask llama.cpp about code I'm working on, so I paste it to the terminal running main in interactive mode.

Whenever there are backslashes, console.cpp treats that as end of input and begins responding.

I don't want that, of course.

I modified a march/april pull of llama.cpp too allow me to paste code or other text with backslashes. Now it only ends input if the backslash is on it's own line... If I have the right version here...

I'd write a PR, however: the fact that nobody else has complained inability to paste code with backslashes, suggests I might be using llama.cpp wrong.

Why isn't anyone complaining about this?
Would you like to review my fix?
