Consecutive emphasis miss

[flintforge]

The \space in the post-emphasis regex is consumed by the regex.
*bold* *bold* *bold*
renders
bold *bold* bold

The stub/editor isn't up to date so I gave up on the pull request or exhaustive testing but a partial fix looks like this :

# parser.js +566
while ((match = emphasisPattern.exec(text))) {
      var whole  = match[0];
      var pre    = match[1];
      var marker = match[2];
      var body   = match[3];
      let post = []
      if (match.index === emphasisPattern.lastIndex) {
	 emphasisPattern.lastIndex++;
	 post = match[4];
      }

[...]

# parser.js +659
buildEmphasisPattern() {
	return new RegExp(
		"([" + this.preEmphasis + "]|^|\r?\n)" +     // \1 => pre
		"([" + this.markers + "])" +                 // \2 => marker
		"([^" + this.borderForbidden + "]|" +        // \3 => body
		"[^" + this.borderForbidden + "]" + this.bodyRegexp +
		"[^" + this.borderForbidden + "])" +
		"\\2" +
		"(?=[" + this.postEmphasis + "]|$|\r?)",     // \4 => post
		// flags
		"g"
	);

Incomplete however as this does eat up a space in consecutive emphasis separated by a newline

/ita/ 
/ita/

->
itaita

consecutive emphasis with two separators renders fine
