Text wrapping causes misinterpretation about fastdoc HOT 3 OPEN

@AllenDowney, I think you can adapt this line (in the corresponding jupyter notebook generating this script):

https://github.com/fastai/fastdoc/blob/master/fastdoc/asciidoc.py#L162

to either output['text'] = '\\n'.join(lines) or output['text'] = '+\n'.join(lines), since I believe asciidoctor supports both + and the probably better \ for line continuations. I'm not sure why the wrapping functionality is there in the first place, since most good editors soft-wrap lines, but maybe @jph00 can speak to that (hi! btw).

In any case, you can either remove the wrapping functionality altogether locally, or use my fix above (untested). I can also create a PR for this if it works for you.

@maxpumperla Thanks very much!

@maxpumperla I believe that wrapping is just for cell outputs. Without it, plain text outputs will go off the right-hand edge of the page if they're long.

It would be helpful if one of you could show a reproducible example that I could look at.
