Problem with colons that are not part of the syntax

[Connum]

There's an issue when the text contains colons that are not part of the span syntax. In that case, the colon character gets duplicated.

var rendered = md.render('This is a :span with **bold**::');

expected output:

<p>This is a <span>span with <strong>bold</strong></span>:</p>

actual output:

<p>This is a <span>span with <strong>bold</strong></span>::</p>

see https://jsfiddle.net/eg5La2nq/21/

When you change

  token.content = ch + ch;

to

  token.content = ch;

in the for-loop of the tokenize function, the output is as intended.

But I wonder why that line has been this way in the first place?

This seems to be related to the issue here (which I am seeking fix for):

@Connum - is the solution you mentioned at the following line?

@mmilczewski - is this the same solution you came up with?

How can we update this repo and the npm package with fix?
