HTML to Markdown: extra newline characters around un-converted tags

[andosteinmetz]

I'm encountering an issue where two newlines (i.e. markdown paragraphs) are inserted after <span> elements. The same happens if it is a <div> or a made-up <pqr> tag.

Here's a very simple test case:

const showdown = require('showdown');

const converter = new showdown.Converter();

const sampleText = '<p>A test <span>case</span> to see if I can <span>reproduce</span> the extra newline <span>problem</span>.</p>';

const ret = converter.makeMarkdown(sampleText);

console.log(ret);

Where I'd expect the result to be:
A test <span>case</span> to see if I can <span>reproduce</span>the extra newline <span>problem</span>.\n\n

I get:
A test <span>case</span>\n\n to see if I can <span>reproduce</span>\n\n the extra newline <span>problem</span>\n\n.

I don't expect this is the desired behavior... Is there an option I'm missing that would solve this problem? Or is it a bug?

UPDATE:
I seem to have fixed the problem for myself by overriding showdown.makeMarkdown.node, where rather than

default: 
  txt = node.outerHTML + '\n\n';
  break;

I have:

  default:
    txt = node.outerHTML;
    break;
}

Thanks. I will look into it.

@SyntaxRules This is still an issue, and I can't figure out how to override it like @andosteinmetz did.
